This makes a great arduino RF sensor station. Using RadioHead "RH_RF95.h" library. I have several off them, send data, go to sleep, send data again, sleep. If your receiving RF on a different type board you need to make sure your data structure is the same size in bytes because not all MCU's are the same. I found using a "short" is most compatible. 1. I used the "Adafruit Feather 32u4" board in the adruino IDE. Pinouts match the 32u4 feather 2. Sleep current is 0.13ma using "LowPower.h" library which also has sleep interrupt to wake up. 3. Enable pin is great if you wont to use a voltage detect to shut down the regulator if Battery gets low. 4. It has a solder jumper to up the charge current to 500ma. I have a 5v solar panel plugged into the 5V pin with a large 4700uf cap. 5. Uses the standard JST 2mm LiPo battery connector and it charges battery fine. Battery connector is on top easy to access. 6. You can put it to sleep for how ever long you want by calling a "for" loop. int i; for (i = 0; i < sleepCycles; i++) {LowPower.powerDown(SLEEP_8S, ADC_OFF, BOD_OFF);} 7. Has a onboard battery voltage divider to read the battery voltage using pin A9. 8. Adjustable antenna is nice 9. Fits bread board with an extra row of pins on each side If you only need it as a RF station to send data, no OLED or WiFi this board is way better then the Heltec WiFi Lora esp32 kit board which Im swapping all mine out for this LoRa32u4 Board. The only pain is ass with all 32u4 MCU's is the serial monitor and sketch upload is a bit troublesome till you figure it out. Need to hit the reset button once upload starts.

I would suggest only powering them with a 1A USB output. I bought a LiPo battery to power it and found out that the polarity is reversed on the battery, so be careful of that issue as well. Plugged reversed the polarity on the LiPo and found out that it would not power from the JST plugin that is made for the battery. My solution was to splice the Micro USB, LiPo, and male JST together to power it by the battery through the USB and use the JST to recharge the battery with the board. As far as other functionality it works good so far. Used some code from the radio head library and modified it to send communication from one board to another while being externally powered. Suggest using adafruit feather libraries with Arduino IDE for board support. If you look on the Adafruit website it will give you step by step instructions on how to configure everything. ## Frequently Bought Together - 2 Sets LoRa32u4ii Lora Development Board Module, JST-PH2.0mm-2P Connector, IPEX Antenna, ATmega32u4 SX1276 HPD13A 915MHz 868MHz, for Arduino UNO Mega 2560 Nano - 4PCS Breadboards Kit Include 2PCS 830 Point 2PCS 400 Point Solderless Breadboards for Proto Shield Distribution Connecting Blocks - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/111798969-2-sets-lora32u4ii-lora-development-board-module-jst-ph2-0mm](https://www.desertcart.in/products/111798969-2-sets-lora32u4ii-lora-development-board-module-jst-ph2-0mm) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-21*
