micro: IO-BOX is a micro:bit multifunctional expansion board with on-board Li-ion battery power, delicate appearance and easy to use. Features numerous functions on the 6cm x 6cm board such as 2-way driver motor, 9-way IO port, 2-way I2C port, 1-way serial port, 1-way buzzer, 4-way RGB LED, Li-ion battery box, charge circuit and emergency power interface. Also features short circuit and reverse connection protection for it to further improve the safety in using Li-ion battery. In order to provide a stable power supply, the board employ high cost boost-buck power management solution. As a motor’s instantaneous current can reach up to 1A at its starting instant which is a big challenge for power supply. So the board carried out a strict test on our product and two TT motors keep rotating forward and reversely continuously and even in such a condition, board and motor can still work about 1.5 hours until running out of the battery.
