microcontroller

Teensy 4.1 can be upgraded with up to 16 Megabytes of PSRAM. Here I describe the process.

ESP8266 is Wi-Fi microchip which can be programmed just like a normal Arduino board. For that purpose some additional software needs to be installed inside the Arduino IDE.

Blink LED is a Hello World! application for micro-controllers. If you manage to get it running, you can assume that you are all setup and ready for further developments on your board. In this blog item I will cover how to do that on a STM32F407 Discovery board.
