Pico:ed V2 is a development board based on Raspberry Pi RP2040 MCU. It uses a dual-core Arm Cortex-M0+ processor with 264KB RAM. The front of the board contains two buttons and a 7x17 dot matrix screen, which can be conveniently used for classroom teaching.
You'll recognize the price along with the basic shape and size, so you can simply drop your new Raspberry Pi into your old projects for an upgrade; and as always, we've kept all our software backward-compatible, so what you create on a Raspberry Pi 4 will work on any older models you own too.
