Specs
Raspberry Pi Pico 2 is a low-cost, high-performance microcontroller board with flexible digital interfaces. Key features include:
- RP2350 microcontroller chip designed by Raspberry Pi in the United Kingdom
- Dual Cortex-M33 or Hazard3 processors at up to 150MHz
- 520KB of SRAM, and 4MB of on-board flash memory
- USB 1.1 with device and host support
- Low-power sleep and dormant modes
- Drag-and-drop programming using mass storage over USB
- 26× multi-function GPIO pins including 3 that can be used for ADC
- 2× SPI, 2× I2C, 2× UART, 3× 12-bit 500ksps Analogue to Digital Converter (ADC), 24× controllable PWM channels
- 2× Timer with 4 alarms, 1× AON Timer
- Temperature sensor
- 3 × Programmable IO (PIO) blocks, 12 state machines total for custom peripheral support
- Flexible, user-programmable high-speed IO
- Can emulate interfaces such as SD Card and VGA
The Raspberry Pi Pico 2 comes as a castellated module which allows soldering direct to carrier boards, while the Pico 2 with headers comes with pre-soldered headers.
Difference from Pi Pico
Pico 2 improves in the following ways from the original Raspberry Pi Pico board:
- double the on-board flash (2 MB → 4 MB)
- an upgrade from RP2040 to RP2350, which includes the following improvements:
◦ higher core clock speed (133MHz → 150MHz)
◦ double the on-chip SRAM (264 kB → 520 kB)
◦ more powerful Arm cores (Dual-core cortex M0+ → Dual Cortex-M33)
◦ RISC-V cores (none → Hazard3)
◦ new security features, including Arm TrustZone for Cortex-M, signed boot, 8 kB of antifuse OTP for key
storage, SHA-256 acceleration, a hardware TRNG, and fast glitch detectors
◦ upgraded interfacing capabilities, increasing from 2 PIO blocks (8 state machines total), to 3 PIO blocks (12
state machines total)
