One of the most popular microcontrollers is ATSAMD21G18A (further - SAMD21). It is a powerful MCU with the Cortex M0+ architecture. Module BOKRA SAMD21 Lite is the world's smallest board with this MCU, designed in the mikroBUS format and having mikroBUS slot and I2C bus.

Frequency – 48 MHz. MCU flash memory - 256 kB, RAM - 32 kB. The microcontroller supports up to six serial interfaces (SERCOM), each of which can be configured as I2C, USART, SPI or LIN-slave. One USB 2.0 channel is also available. The microcontroller contains one 12-bit ADC (speed - up to 350 ksps) and 10-bit DAC (speed - up to 350 ksps).

Debug Interface - SWD. External connectors - I2C and mikroBUS slot. Input power supply - 5V. The voltage regulator is Microchip's MIC5528, providing 500 mA output current. The module has a RESET button and three LEDs (power and two software-controlled). The size of the BOKRA SAMD21 Lite module is 28.6 x 25.4 mm.

The ATSAMD21G18A microcontroller is widely used in the following areas:

• Industrial Applications
• Automotive
• Remote I / O
• Wireless controllers
• Consumer devices
• Household appliance
• Keyboards and Human Interface screens

Easy create and product.
