STMicro Introduces the First STM8 Nucleo Boards, STM8 Arduino IDE Support

While development boards based on STMicro STM8 8-bit MCU such as the “one dollar board” or the official STM8 Discovery boards have been around for several years, STMicro had yet to release a Nucleo board based on the microcontroller. The company has now unveiled not one, but two such boards with NUCLEO-8L152R8 and NUCLEO-8S208RB. Both boards will look similar as only the MCU differs. The former features a 16 MHZ MCU with 64 kB flash and 4KB SRAM, while the latter comes with a 24 MHz MCU with 128 kB flash, and 6KB SRAM.STM8 Nucleo board specifications: MCU (One of the other) NUCLEO-8L152R8 – STMicro STM8L152R8T6 8-bit MCU @ 16 MHz with 64 kB flash, 2KB EEPROM, 4KB SRAM NUCLEO-8S208RB – STMicro STM8S208RBT6 8-bit MCU @ 24 MHz with 128 kB flash, 2KB EEPROM, 6KB SRAM 4x LEDs – USB communication (LD4), 5V STLINK (LD3), User (LD2), Power (LD1) 2 […]
