... Overview 2 Overview 2.1 Power supply (JP1, JP3) The STM8L15LPBOARD is powered by a lithium battery CR2032 when jumper JP3 is closed. Depending on the JP1 position, the MCU consumption auto-measurement circuit can be used. Table 1. JP1 setting JP1 position VDD power is directly connected to MCU VDD when JP1 is set as shown to the left (default setting) ...

... STM8L15LPBOARD 3 Demonstration The jumper JP1 must be in the required position before launching the demo: if automatic consumption measurement is not used, JP1 must be between pins 1 and 2, if automatic consumption measurement is used, JP1 must be between pins 2 and 3. The Wakeup button is used: to exit each mode and go to the next mode proposal, to answer “ ...
