Product Update [2022.02.25]

"M" version main board released (PN:109-15800-00M). The changes include:

The ciucuits of the breakout boards BOB1 (JYE118, battery charger) and BOB2 (JYE117, power switch) have been integrated on the main PCB.
Added a USB-Uart converter on the main PCB (U20, CH340N). This allows serial data transfer and firmware upgrade throuth the powering USB port.

Important Notes

Before beginning to work on the WAVE2 DIY kit, please make sure you have all the tools ready and some soldering experience. Handle soldering iron and all components with care, and keep out of reach from children.

About the Battery
Please note the battery is not included with the WAVE2 DIY kit, however the kit does come with battery wires with matching header. To help you source your own batteries, please source batteries smaller or equal to the following sizes:
L x W x H = 62mm x 40mm x 5mm; or
L x W x H = 68mm x 31mm x 5mm

Recommended battery size:
L x W x H = 59mm x 37mm x 5mm / 1200mAh (usually specified as 503759 1200mAh)
