No UART No AnalogIn support No AnalogOut support No PWM support If you are using Blinka in FT232H mode, then keep in mind these basic limitations. SPI and I2C can not be used at the same time since they share the same pins. GPIO speed is not super fast, so trying to do arbitrary...

Update pico-sdk to version 2.1.0. #9831. Thanks @eightycc. SAMx SiLabs Spresense STM Individual boards Adafruit Floppsy RP2040: add board.DISPLAY; update pins. #9869, #9833. Thanks @jepler. LILYGO T-Watch 2020 V3: restore serial connection. #9916. Thanks @Neradoc. Oxocard Connect:...
Overclock your Pico! It's safe to double the RP2040 speed, Raspberry Pi officially supports up to 200 MHz. CircuitPython will adjust its internal timings, but you should do this change before creating any peripheral objects like UARTs or displays....
Bradan Lane RP2040 Explorer Badge: reassign UART pins to IR; add frozen modules.#9389. Thanks@bradanlane. Espressif ESP32-S3-DevKitM-1: Add missing pins.#9287. Thanks@fetsnleds. M5Stack Cardputer improvements:#9280,#9273. Thanks@bill88t. ...
Even so, this guide will focus mostly on PWMAudioOut on Pico RP2040 because it's quick and simple, but any of the above will work. Audio out hardware Because there are many audio output methods, there are many different circuits. Ready-made boards The simplest will be ready-made boards,...
