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 […]

$3.40 WeAct STM32WB55 board offers Bluetooth LE 5.4 and 802.15.4 (Thread/Zigbee/Matter) connectivity

WeAct STM32WB55 is an inexpensive development board based on STMicro STM32WB55 Arm Cortex-M4 wireless SoC with Bluetooth LE 5.4 and an 802.15.4 radio for Zigbee, Thread, and Matter connectivity that sells for just $3.40 shipped. STMicro STM32WB55 wireless microcontroller was introduced in 2019, and we have covered a few development boards such as the official P-Nucleo-WB55 development pack, the STM32WB-Feather board, and the MRK-SharkyPro following the Arduino MRK form factor. All those boards would go for about $40, but thanks to China manufacturing and procurement “magic” and the cutting of a few features, the WeAct STM32WB55 board sells for just a fraction of the price making it even cheaper than the company’s ESP32-H2 board with similar connectivity options. WeAct STM32WB55 specifications: Wireless MCU – STMicro STM32WB55CGU6 CPU Arm Cortex-M4 application core @ 64 MHz Arm Cortex-M0+ Bluetooth co-processor @ 32 MHz Memory – 256 KB of SRAM Storage – 1 […]
