Description Based on TI QI standard wireless charge solutions, can receive power from any QI compatible transmitter. Coil size 40×28 mm outside, and 22×10 inside, inductance is about 10uh, compatible with QI standard. Includes two 10CM soldered power wires, negative and positive. BQ51013B gives 5V up to 1A receiving capability. Tested charging current is about 0.5-0.8A for our board. Can be designed as USB 5V charge. Board size 40x25mm, 0.6mm thickness. BQ51050 supports 4.2V lithium battery up to 1A charge management. Tested charging current is about 0.6-0.8A when battery 3.7V, 0.2-0.3A when battery 4.1V, stop charge when battery voltage nearly reach 4.2V. On board power indicator, on when charging, off when battery is full. Configurable charge current by resistor, default use 510R for 1A. Board size 31x24mm, 0.6mm thickness, good for embedded projects. Must connect to a lithium battery first, otherwise this can not work. Documentation please see on this page.
