MicroPython 1.20 released with Raspberry Pi Pico W support, mip package manager, smaller footprint

Damien George has recently announced the release of MicroPython 1.20 with support for the Raspberry Pi Pico W board., a new lightweight package manager called mip, a smaller footprint thanks to the use of compressed type structs, and many other changes. mip package manager The new mip package manager uses a custom protocol optimized for embedded systems to query and install packages, and intends to replace upip for installing packages from micropython-lib or any URL. Mip can be run directly on a device, as long as it has network connectivity, or via mpremote from a host computer. Damien explains all pure-Python drivers have been moved from the micropython repository to the micropython-lib repository as part of the change in order to make it easier to install the packages needed for a given project. MicroPython is getting smaller The MicroPython binary size has been reduced by many kilobytes for all ports […]

Control 8 relays with the Raspberry Pi Pico using PicoRelay8 or Pico-Relay-B

8086 Consultancy’s PicoRelay8 is a baseboard for the Raspberry Pi Pico (W) board equipped with eight 28V DC / 10A Normally Open relays that be used for all sorts of automation projects, while Waveshare Pico-Relay-B also supports eight relays with both DC and AC loads and comes with some extra features. PicoRelay8 PicoRelay8 board specifications: Supported MCU board – Raspberry Pi Pico or Pi Pico W, and it may also work with “mostly” compatible boards such as the Banana Pi BPI-Pico-RP2040 or BPI-PicoW-S3, WeAct RP2040, and others as long as all GPIO used on the PicoRelay8 are exposed on the same pins. Relays 8x HF3FF/005-1HST relays rated for 28V DC/10A, as well as 10A/250V AC and 15A/125V AC, but the board is not designed to get power from the mains (safety-wise), so it’s only really suitable for DC loads Each relay has a 2-pin terminal block attached to it.
