The battery pack also serves as a stand for the solar panel while charging, or for your micro:bit! Micro:bit sold separately. HOW IT WORKS MEASURING THE BATTERY VOLTAGE You can create a simple program on the micro:bit to measure the battery voltage using a jumper wire. Connect a jumper from the Battery Voltage Monitor pin on the Solar Battery to the P0 input on the micro:bit. Create a program that will loop on analog read P0 and printout the results. The reading will be between 0 and approximately 400. For example a battery voltage of 4.27 volts will give 1.78 volts at the battery monitor terminal. ( 4.27 2.4 = 1.78) and a value of 391 in the analog read. SPECIFICATIONS USB Connector Max.
