LoRa Radio Node v1.0 from IOTMCU

PCB กึ่งสำเร็จรูป ยังไม่ได้ลงโปรแกรมและไม่รวมรางถ่านหรือแบตเตอรี่ (3.7V 14500)

Feature:

• Power supply: 3.7V 14500 Lipo battery or 3.7-12V DC power (VCC GND: 2PIN 2510-I Type connect)
• Size: 40mm x 60mm
• ATmega328P @ 8MHz with 3.3V logic/power
• 3.3V regulator with 500mA peak current output
• Hardware Serial, hardware I2C, hardware SPI support
• 1 x PWM pins: D3
• 12 x analog inputs: A0 A1
• Pin #13 BLUE LED for general purpose blinking
• 2 mounting holes
• Reset button This LoRa Radio Node uses the extra space left over to add an RFM95 LoRa 868/915MHz radio module. These radios are not good for transmitting audio or video, but they do work quite well for small data packet transmission when you need more range than 2.4 GHz (BT, BLE, WiFi, ZigBee).
• SX1276 LoRa® based module with SPI interface
• Packet radio with ready-to-go Arduino libraries
• Uses the amateur or license-free ISM band: ITU "Europe" license-free ISM or ITU "American" amateur (with amateur band limitations)
• +5 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)
• ~300uA during full sleep, ~120mA peak during +20dBm transmit, ~40mA during active radio listening.
• Simple wire antenna or spot for uFL connecto
