## Customer Reviews

### ⭐⭐⭐⭐⭐ Good Board, works
*by T***K on July 31, 2019*

I ordered this board from a couple vendors so review will be the same. 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 feather2. 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 nice9. Fits bread board with an extra row of pins on each sideIf 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 wish it had an SMA connector for the antenna

### ⭐ No Getting started or document
*by M***N on April 1, 2025*

zero docuemts, zero support.even their "tutorial" video on the Amazon page is so low quality, you cannot see what is going on, and even worse, they are not talking in English

### ⭐⭐⭐ Decent board but could not power by JST & LiPo
*by T***D on April 23, 2023*

I bought four of these boards because I fried one of the by hooking it up to a 2.4A USB output. 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.
