Raspberry Pi Pico
https://en.wikipedia.org/wiki/Raspberry_Pi#Raspberry_Pi_Pico “Raspberry Pi Pico was released in January 2021 with a retail price of $4. It was Raspberry Pi’s first board based upon a single microcontroller chip; the RP2040, which was designed by Raspberry Pi in the UK. The Pico has 264 KB of RAM and 2 MB of flash memory. It is programmable in C, C++, Assembly, MicroPython, CircuitPython and Rust. The Raspberry Pi Foundation has partnered with Adafruit, Pimoroni, Arduino and SparkFun to build accessories for Raspberry Pi Pico and variety of other boards using RP2040 Silicon Platform”
“On 30 June 2022, the Raspberry Pi Pico W was launched, a version of the Pico with 802.11n Wi-Fi capability, for US$6. The CYW43439 wireless chip in the Pico W also supports Bluetooth, but the capability was not enabled at launch”

MicroPython
https://en.wikipedia.org/wiki/MicroPython “MicroPython is a software implementation of a programming language largely compatible with Python 3, written in C, that is optimized to run on a microcontroller. MicroPython consists of a Python compiler to bytecode and a runtime interpreter of that bytecode. The user is presented with an interactive prompt (the REPL) to execute supported commands immediately. Included are a selection of core Python libraries; MicroPython includes modules which give the programmer access to low-level hardware. MicroPython does have an inline assembler, and that code will run at full speed”
“In July 2017, MicroPython was forked to create CircuitPython, a version of MicroPython with emphasis on education and ease of use. MicroPython and CircuitPython support somewhat different sets of hardware (e.g. CircuitPython supports Atmel SAM D21 and D51 boards, but dropped support for ESP8266). As of version 4.0, CircuitPython is based on MicroPython version 1.9.4”
