| + | |||
| + | Recommended 2.5A supply, but that includes max of 1.2A for USB ports, so 1.3A board. Type 500mA. With LoRa board, maybe 1.5A total needed at 5V. | ||

| + | 7.5W. | ||
| + | |||
| + | About 700mA max at 11V - i.e. a nearly empty lead acid battery powering the CAN bus. NMEA micro cables should be 22 AWG for power. ~62R / km, 124R with return. ~1R2 for 10 meters. Seems ok. | ||
