IO-BOX Expansion Board for micro:bit

15 items left

INTRODUCTION

The micro:IO-BOX is a micro:bit multifunctional expansion board with onboard Li-ion battery power, a delicate appearance, and is easy to use. DF Robot integrated numerous functions on the 6cm×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, emergency power interface, and more. There is an outer protective cover for the product to make it more durable.

 

In order to provide a stable power supply, there is a high-cost boost-buck power management solution. A motor’s instantaneous current can reach up to 1A at it starts instantly, which is typically a big challenge for the power supply. DF Robot carried out a strict test on their product: they made two TT motors that keep rotating forward and reversely continuously, and even in such a condition, the board and motor can still work about 1.5 hours until running out of battery. In normal operation, the battery can work for over 6 hours.
