The Raspberry Pi team has released a chip-level board featuring the RP2040 with a 40nm architecture: Raspberry Pi Pico.
RP2040 Specification:
- Dual-core Arm Cortex-M0+ @ 133MHz
- 264KB RAM
- Support for up to 16MB Flash memory via a dedicated QSPI bus
- DMA controller
- 30 GPIO pins, 4 of which can be used as analog inputs
- 2 UART, 2 SPI, and 2 I2C controllers
- 16 PWM channels
- USB 1.1 controller with host mode support
- 8 Raspberry Pi I/O (PIO) programmable state machines
- USB mass-storage boot mode with UF2 firmware support
The Raspberry Pi Pico is designed as an original, low-cost ($4) board for the RP2040. It contains the RP2040 with 2MB of flash memory and a power management chip that supports input voltages from 1.8 to 5.5V. This allows the Pico to be powered from various sources, including two or three AA batteries in series or from a single lithium-ion battery.
Boards based on the RP2040 chip will also soon be available from third-party manufacturers:
