Carry Module Version 1.0

Power Source: 4 AA batteries rated at 1.5V each connected in series in 2 wired battery boxes.

Source Voltage: 6 Volts

LoRa Board: DIYmalls 915MHz ESP32 LoRa OLED 0.96 SX1276 Module + LoRa Antenna U.FL IPEX to SMA

Heltec Module requires 3.3 volts or 5 volts to function, so a voltage divider circuit is required.

Voltage Divider Circuit Components

• 1x 220 Ohm Resistor
• 1x 100 Ohm Resistor
• 1x 1000 Ohm Resistor
