Customer:

I purchased an Inkplate 5v2 for educational purposes and want to display the battery level on the Inkplate. Is this possible with the 5v2 or do I need additional hardware to accomplish this?

Original message (German)

ich habe mir ein Inkplate 5v2 für Schulungszwecke gekauft und möchte den Akkustand auf meinem Inkplate anzeigen lassen. Ist das mit dem 5v2 möglich oder benötige ich weitere Hardware um das zu realisieren?

 **************************************************
 * @file        Inkplate5V2_Read_Battery_Voltage.ino
 * @brief       Battery voltage reading example for Soldered Inkplate 5v2.
 *
 * @details     Demonstrates how to read the connected Li-ion/Li-Po battery
 *              voltage using Inkplate's built-in battery measurement circuitry.
 *              The example shows how to obtain the battery voltage value in
 *              software and display or process it as needed.
 *
 *              Battery voltage reading is enabled through the onboard
 *              circuitry, and typically requires enabling the battery
 *              measurement path in hardware (see Inkplate documentation).
 *              Accuracy depends on battery condition and load. Expected output
 *              is the measured battery voltage value reported by the program.
 *
 * Requirements:
 * - Board:      Soldered Inkplate 5v2
 * - Hardware:   Inkplate 5v2, USB cable, 3.6-4.2 V Li-ion/Li-Po battery (JST connector)
 * - Extra:      None
