**DevBoard:** Notice that when using this ComBoard together with the [DPP DevBoard](https://gitlab.ethz.ch/tec/research/dpp/hardware/pcb/app_devboard), `BOLT_VCC` (VCC Select Pin 6) and `COM_VCC` (VCC Select Pin 8) are connected on the ComBoard. Therefore, for power measurements of the ComBoard, _both_ jumpers (`C` and `B`) must be disconnected.
**FlockLab:** The boards that are available as targets on FlockLab (`DPP2LoRa` and `DPP2LoRaHG`) have the resistor `R200` (see [schematic](https://gitlab.ethz.ch/tec/research/dpp/hardware/pcb/com_lora/blob/master/outputs/DPP2_ComBoard_LoRa_rev_1.PDF)) placed with a 220 Ohm part (measured on a single board). Therefore, it is essential that Pin _PB.3_ is not left floating, as this can lead to significant observable leakage currents up to 50mA.
**FlockLab:** The boards that are available as targets on FlockLab (`DPP2LoRa` and `DPP2LoRaHG`) have the resistor `R200` (see [schematic](https://gitlab.ethz.ch/tec/research/dpp/hardware/pcb/com_lora/blob/master/outputs/DPP2_ComBoard_LoRa_rev_1.PDF)) placed with a 220 Ohm part (measured on a single board). Therefore, it is essential that *Pin _PB.3_* (`COM_GPIO2`) is not left floating, as this can lead to significant observable leakage currents up to 50mA. Similarly, *Pin _PH.3_* (`COM_GPIO1`) should not be used and always remain cleared, as FlockLab is actively driving it low because it is connected to `TARGETx_PROG`.
