Banana Pi BPI-Pico-RP2040

Banana Pi Release New Raspberry Pi Pico Alternative

Posted on

The Raspberry Pi Pico‘s “Pi Silicon” RP2040 SoC was the plentiful source of microcontroller brains during a long period of supply chain woes. It was natural for official partners (Adafruit, SparkFun, Arduino and Pimoroni) to release their own spins on the $4 microcontroller, and others including Banana Pi followed suit. For its latest model, the Banana Pi BPI-Pico-RP2040 we see the same 40 pin form factor but there are a few differences between the official Pico and Banana Pi’s

Let’s start with the price. Coming in at a MSRP of $6.58 (currently discounted to $5.26) the board is $2 more than an official Raspberry Pi Pico. For the additional dollars we get an onboard WS2812B “NeoPixel” RGB LED connected to GPIO3 (PDF) and a 4 pin JST-PH socket. This socket is more commonly referred to as Stemma QT, Qwiic or QW/ST and in reality it breaks out the I2C interface (I2C0 on pins GP8 and 9 to be specific) for use with compatible devices.
