Many companies have come up with their Raspberry Pi RP2040 boards. Adafruit being one of them has unveiled its two boards featuring RP2040 SoC. Meet Adafruit Feather RP2040, and Adafruit ItsyBitsy RP2040 supporting the CircuitPython port for programming. The boards would be an interesting combination of Adafruit’s design with the Pi silicon SoC.
Adafruit Feather RP2040
Talking more about the Adafruit Feather RP2040, it comes with 21GPIO pins which are less than the Raspberry Pi Pico’s 40 GPIO pins. The board being Adafruit’s architecture thus it combines the “popular Feather ecosystem and form factor with Raspberry Pi Silicon” As most of the RP2040 boards Adafruit Feather also comes with 264KB RAM and 4MB of SPI Flash.
There is also a provision of a 200mA charger as the JST connectors supporting Lithium-Ion and Lithium Polymer batteries. For displaying the charging status there is an inbuilt LED on the board. It also comes with a STEMMA QT connector, that allows fast interfacing with the supporting devices. It is a connector breakout for one of the two I2C channels.
Adafruit ItsyBitsy RP2040
Adafruit’s ItsyBitsy RP2040 comes with 23 GPIO pins which are more than Adafruit Feather RP2040 featuring 21 GPIO. It also has a 3.3V regulator and 24MHz crystal for efficient clock cycles. “A Vhigh output pin allows the ItsyBitsy to drive high-powered peripherals such as servos and NeoPixels.”
Both the boards work at a frequency of 125 MHz which is slightly less than the Raspberry Pi Pico which works at 133MHz. The dimensions of Adafruit Feather RP2040 are 50.8mm x 22.8mm x 7mm, whereas for Adafruit ItsyBitsy the dimensions are 36mm x 18mm x 4mm. Both the boards have their software support in CircuitPython, MicroPython, and C/C++.
Adafruit Feather RP2040 is available for $11.95 and Adafruit ItsyBitsy RP2040 not yet release, so the pricing information is not available. For more information visit the official product page of Adafruit Feather and Adafruit ItsyBitsy.
