RAK3172T in Arduino
As the RAK11300 did not really match my requirements (it uses way too much energy), I looked further and found the RAK3172 which is based on an STM32WLE5CCU6 - an STM32 chip which usually include good powersaving modes. As with the RAK11300, I did not want to go down the Wisblock way and designed my own breakout board:

This was act

Turing Pi 2 - Retrofitting an EMC2301 Fancontroller
The Turing Pi 2 (v.2.4) has actually some secrets that just start to get uncovered. Looking closely at the board, you will find the red marked area with what seems to be an unpopulated 4-pin fan header (J16) and an unpopulated IC spot (U109).

These spots were, as found out by Sam Edwards (CFSworks) actually a place to install Molex 47053-1000 4-p

Install a bootloader onto Turing RK1 eMMC memory
The Turing RK1 is a new Compute Module, made for the Turing Pi 2 board and with compability to the Nvidia Jetson cards in mind. While the board has some impressive specs ( https://docs.turingpi.com/docs/turing-rk1-specs-and-io-ports ) it had one small issue: The used Rockchip RK3588 needed a bootloader on its eMMC to be able t

Repairing a TuringPi 2
Intro
In April 2023 I finally got my TuringPi 2 - happy to finally got it into my hands I plugged it in, headed over to the TuringPi 2 Github ( https://github.com/turing-machines/BMC-Firmware ) got myself the latest BMC firmware and started to flash it. Thats when things got wrong: The power supply coils started to screech - and seconds later I was gree

RAK11300 Teardown
About a year ago I got some RAK11300 modules - which are a nice combination of an RP2040 alongside a SX1262 radio on one module - designed a breakout board - tested it - and quickly shelved it. Reason was that this module was somewhat Arduino compliant - as stated - however only with RAKwireless Arduino mbedOS Repo. Alongside of it being a bit.
