Quiz: Choosing the Right Raspberry Pi Product

Test your understanding of the Raspberry Pi Foundation product line and the product decision framework with these review questions.

1. What is a microcontroller?

  1. A complete, general-purpose computer built onto one circuit board capable of running Linux
  2. An integrated circuit that combines a processor, memory controller, and input/output circuitry into one package
  3. A supply disruption that reduces the availability of memory chips
  4. A small, low-power computer chip designed to run a single program repeatedly, with no operating system
Show Answer

The correct answer is D. A microcontroller is a small, low-power computer chip designed to run a single program repeatedly, with no operating system and no desktop — it starts running code immediately on power-up. Option A describes a single board computer instead. Option B describes a system on chip, the broader packaging concept both board families use. Option C describes a RAM shortage, an unrelated supply-chain issue.

Concept Tested: Microcontroller

2. What is a single board computer?

  1. A complete general-purpose computer built onto one circuit board, capable of running a full operating system
  2. A small chip designed to run one program repeatedly with no operating system
  3. A category of hardware grouped by approximate cost
  4. A structured set of questions that narrows hardware options to a recommendation
Show Answer

The correct answer is A. A single board computer (SBC) is a complete, general-purpose computer built onto one circuit board, capable of running a full operating system like Linux and supporting a keyboard, mouse, and monitor. Option B describes a microcontroller instead. Option C describes a price tier, and option D describes the product decision framework — both unrelated definitions.

3. Which chip powers the original Raspberry Pi Pico?

  1. RP2350
  2. RP2040
  3. Broadcom BCM2712
  4. RP2712
Show Answer

The correct answer is B. The original Raspberry Pi Pico runs on the RP2040 chip, an SoC designed by the Raspberry Pi Foundation itself. The RP2350 (option A) powers the newer Pico 2 instead. The Broadcom BCM2712 (option C) powers the Pi 500+ and Pi 5, not any Pico board. RP2712 (option D) is not a real chip mentioned in the chapter.

4. What is total cost of ownership?

  1. The price printed on a board's product page
  2. The category of hardware grouped by approximate cost
  3. The full cost of using hardware over its useful life, including the board plus every accessory and ongoing expense
  4. The length of time a board remains usable before becoming obsolete
Show Answer

The correct answer is C. Total cost of ownership is the full cost of using a piece of hardware over its useful life, including the board itself plus every accessory, replacement part, and ongoing expense needed to keep it running. Option A describes only the sticker price, which the chapter explicitly says is just a starting point. Option B describes price tier, and option D describes device lifespan — related but distinct ideas.

5. According to the chapter, why does the Raspberry Pi 500+ cost significantly more than a bare Raspberry Pi 5 board, even though both use the same Broadcom BCM2712 chip?

  1. The Pi 500+'s price includes a keyboard, case, and RGB lighting hardware built around the same chip
  2. The Pi 500+ uses a faster clock speed than the Pi 5
  3. The Pi 500+ requires a more expensive version of the RP2350 chip
  4. The Pi 5 is a microcontroller while the Pi 500+ is a single board computer
Show Answer

The correct answer is A. The chapter explains that price doesn't just track chip capability — it also tracks what else you're buying. The Pi 500+'s price bundles in a keyboard, case, and per-key RGB lighting hardware, while a bare Pi 5 board still needs a separate power supply, storage, and case. Option B is false since both share the same BCM2712 chip. Option C invents an unrelated chip, and option D misclassifies the Pi 5, which is also a single board computer.

6. What distinguishes a system on chip (SoC) from a set of separate chips wired together on a circuit board?

  1. An SoC can only be used in single board computers, never microcontrollers
  2. An SoC always includes built-in Wi-Fi hardware
  3. An SoC is any chip manufactured by Broadcom
  4. An SoC combines a processor, memory controller, and input/output circuitry into a single physical package
Show Answer

The correct answer is D. A system on chip integrates a processor, memory controller, and input/output circuitry into one physical package instead of wiring together separate chips. Option A is incorrect because both the microcontroller-family RP2040/RP2350 and the SBC-family BCM2712 are SoCs. Option B is false — Wi-Fi is only present on specific boards like the Pico W, not a defining feature of every SoC. Option C wrongly limits SoCs to one manufacturer.

7. Why can a board's price rise even though the board's design and specifications haven't changed?

  1. Vendor documentation becomes outdated and must be repurchased
  2. The product decision framework recalculates price tiers automatically
  3. A RAM shortage or other supply disruption raises the cost of components the board depends on
  4. Device lifespan estimates are updated annually by the manufacturer
Show Answer

The correct answer is C. A RAM shortage is a supply disruption in memory-chip manufacturing that reduces availability and drives up prices across products that depend on those chips, even when the board itself is unchanged. Option A misapplies documentation, which has no bearing on price. Option B mischaracterizes the product decision framework as an automatic pricing tool rather than a buyer's checklist. Option D describes an unrelated concept, device lifespan.

8. Which statement correctly contrasts the RP2040/RP2350 chips with the Broadcom BCM2712 chip?

  1. The RP2040/RP2350 were designed by Broadcom, while the BCM2712 was designed by the Raspberry Pi Foundation
  2. The RP2040/RP2350 were designed by the Raspberry Pi Foundation and power the Pico-family microcontrollers, while the BCM2712 is a Broadcom-designed chip that powers the Pi 500+ and Pi 5
  3. Both chip families are designed by the same outside chipmaker
  4. The BCM2712 is used only in microcontrollers, while the RP2040/RP2350 power single board computers
Show Answer

The correct answer is B. The RP2040 and RP2350 were designed by the Raspberry Pi Foundation itself and power the Pico-family microcontrollers, while the Broadcom BCM2712 is designed by an outside chipmaker, Broadcom, and powers the Pi 500+ and Pi 5 single board computers. Option A reverses the designers. Option C incorrectly claims a shared designer. Option D reverses which chip family belongs to which board type.

Concept Tested: Broadcom BCM2712

  1. A single board computer like the Pi 5, because it has the most processing power
  2. The Raspberry Pi 500+, because its RGB keyboard lighting is useful for indicating sensor state
  3. Whichever board has the fastest clock speed, since clock speed is the primary deciding factor
  4. A Pico-family microcontroller, because the project doesn't need an operating system, camera, or desktop environment
Show Answer

The correct answer is D. The framework's first question is what the project needs to do — a project that only reads a sensor and blinks a light rarely needs an operating system, so a Pico-family board fits best and keeps cost low. Options A and B recommend single board computers whose extra capability (or keyboard lighting) isn't needed here. Option C misapplies clock speed as the primary factor, which the chapter explicitly warns against.

10. A classroom teacher is choosing between two boards with the same price and similar specs. Board X has thin, outdated vendor documentation; Board Y has a clear pinout diagram and getting-started guide. Based on the chapter's framework, what is the most likely consequence of choosing Board X for a class of thirty students?

  1. Board X will have a shorter device lifespan regardless of documentation quality
  2. Board X will automatically fail the hardware compatibility check for any accessory
  3. Board X's total cost of ownership will likely increase due to extra troubleshooting time, even though its sticker price matches Board Y
  4. Board X will require a RAM shortage surcharge that Board Y does not
Show Answer

The correct answer is C. The chapter notes that a board with thin or outdated vendor documentation costs extra time troubleshooting later, even if it was cheaper up front — and for a class of thirty, that support burden adds real cost that total cost of ownership captures but the sticker price does not. Option A wrongly links documentation quality directly to lifespan. Option B and D introduce consequences (compatibility failure, shortage surcharges) that documentation quality alone does not cause.
