Raspberry Pi Pico WH is just like the classic Pico but adds pre-soldered headers, a new 3-pin debug connector, and an on-board single-band 2.4GHz wireless interfaces (802.11n) using the Infineon CYW4343 while retaining the Pico form factor. The on-board 2.4GHz wireless interface has the following features:
- Wireless (802.11n), Single-band (2.4 GHz) WiFi with WPA3 and Soft Access Point supporting up to 4 clients
- Bluetooth Low Energy - note this isn't supported in software yet, its just a hardware capability.
- The wireless interface is connected via SPI to the RP2040 microcontroller and has a micropython driver for wireless capability
Due to pin limitations (the Pico brings out all the GPIO) some of the wireless interface pins are shared with the exposed pads:
- The SPI CLK is shared with VSYS monitor, so only when there isn’t an SPI transaction in progress can VSYS be read via the ADC.
- The Infineon CYW43439 SPI DIN/DOUT and IRQ all share one pin on the RP2040. Only when an SPI transaction isn’t in progress is it suitable to check for IRQs.
- The interface typically runs at 33MHz.
RP2040 Chip features:
- Dual ARM Cortex-M0+ @ 133MHz
- 264kB on-chip SRAM in six independent banks
- Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus
- DMA controller
- Fully-connected AHB crossbar
- Interpolator and integer divider peripherals
- On-chip programmable LDO to generate core voltage
- 2 on-chip PLLs to generate USB and core clocks
- 30 GPIO pins, 4 of which can be used as analog inputs
- Peripherals
- 2 UARTs
- 2 SPI controllers
- 2 I2C controllers
- 16 PWM channels
- USB 1.1 controller and PHY, with host and device support
- 8 PIO state machines
