If you’re a fan of tiny microcontroller boards, you’ll be pleased with BOKRA SAMD21 Lite board powered by Microchip SAMD21 Arm Cortex-M0+ MCU, exposing I/Os in a way compatible with MikroBus socket, and adding a Grove connector for good measure. SAMD21 Lite board specifications: MCU – Microchip ATSAMD21G18A Arm Cortex-M0+ microcontroller @ 48 MHz with 256KB flash memory, 32KB RAM Expansion I/Os MicroBus socket with GPIO, SPI, I2C, USART, PWM, DAC, +5V, +3.3V, GND I2C Grove connector 10-pin I/O header with GPIO, USB 2.0, VIN, GND Misc – Reset button, red power LED, 2x user LED (yellow/green), J1/J2 jumper to enable/disable I2C pull-ups Debugging – 4-pin SWD header Power Supply 5V input via VIN MIC5528500 voltage regulator Output current – 500 mA Dimensions -28.6 x 25.4 mm Despite its tiny size, SAMD21 Lite exposes all expect five I/Os from the microcontroller. The Microbus headers and the I2C Grove connector allow it to support hundreds of add-on boards from MicroElektronika or […]
