ESCOberon, an embedded variant of Oberon-2, is available for this MIT-licensed dev board as an alternative to C/C++ programming.

Norwegian-based Tenko has released an open-hardware development board based on STMicroelectronics’ STM32C5 microcontroller family. The compact board follows the familiar Blue Pill form factor while adding USB-C power, onboard USB-to-UART connectivity, and an alternative firmware environment based on Oberon-2. The board uses the recently introduced STM32C551CE, a 32-bit Arm Cortex-M33 microcontroller operating at up to […]
