Designed for short range BT interactions and power savvy projects. Small (48mm x 18mm) and robust board is built around the NINA B306 module, based on Nordic nRF 52840 and containing a powerful Cortex M4F. The board’s architecture is fully compatible with Arduino IDE Online and Offline with dedicated libraries; it has a 9 axis Inertial Measurement Unit (IMU) and a reduced power consumption compared to other same size boards. Clock 64MHz, Flask 1MB, RAM 256KB. Two 15 pin connectors - one on each side of the board.

The keyestudio Leonardo is a microcontroller board based on the ATmega32u4 It has 20 digital input/output pins (of which 7 can be used as PWM outputs), 12 analog inputs, a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. The Leonardo differs from other boards using separate USB-Serial chip in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard. Has fcc and ce certification that they are made from environmentally friendly production technology and materials, made function,voltage, current testing before packaging
