Interesting new micro-controller board and custom chip from Raspberry Pi: Raspberry Pi Pico.
It is programmable with Python and C/C++. Cross-platform toolchain for development on Windows, macOS, and Linux — including, naturally, the Raspberry Pi family itself Supports TensorFlow Lite.
Raspberry Pi is looking to do for the microcontroller market what they’ve already done for single-board computers with the launch of the Pico. The board — priced at just $4 — is based on the RP2040, a dual-core Cortex-M0+ processor designed in house. It designed to be easy to taken into use.
Announcement at Facebook says:
It’s been a big week. We launched something tiny, something new – Raspberry Pi Pico, just for you.
Read all about it, plus everything else that went down at Raspberry Pi in the last few days, in Raspberry Pi Weekly.

Raspberry Pi Pico: DS1307 RTC Module – Keep Track of Time (MicroPython)
In this guide you’ll learn how to interface a DS1307 RTC module with the Raspberry Pi Pico programmed with MicroPython. We’ll cover the basic functioning of the module, how to connect it to the Pico, how to set and keep track of its time. Finally, we’ll create a simple digital clock with an OLED display.
