Description Lora Modules and Features: On board wireless radio SX1278 Lora (315 / 433mhz) or SX1276 Lora (868 / 915mhz) You can purchase alone here. Read more details here. Low power consumption, long transmission distance and low error rate Frequency available for two types: 410MHz~525MHz, 803~930MHz Lead out SX1278 Lora pin IO1, IO2, IO3. Arduino Compatible MCU Atmega328P: Use atmega328P IC with arduino pro mini bootloader as main controller. Arduino sketch can be uploaded via FTDI side interface. Reserved on-board all unused pins or LGT 8F328 with pre-loaded firmware, can support upload arduino sketch normally. On Board Flash Storage: On board SPI flash 8M-bit for data Supported by arduino SPI flash library. (or low power spi flash library from lowpowerlab) You must disable if you want to make it low power, so only turn on when you use it. Battery Charging: On board MCP73831 battery charger IC. Board can be powered by lithium battery, and charge when 5V power supplied to board. On board power LED, and backside charge status LED. Battery voltage level monitoring can be read via A7 analog pin. (1.0 version used to have on D6, if you must use it please contact us for a replacement.)
