2 Sets Assembled ESP32 OLED WiFi Lora Kit 0.96inch OLED Display ESP-32S Bluetooth-Compatible CP2102 Development Board Lora SX1276 915MHZ/868MHZ Antenna Transceiver for Arduino ESP8266 NodeMCU

My screen is already failing. Poor quality. The screen was cracked on the corner near the mounting screw. Check this when it arrives as has lines missing from the display. I bought 2 and the second one is fine. I have emailed heltec and asked them to check this issue. An expensive unit when faulty so soon.

I originally reviewed this product poorly due to suspected failed screens. Come to find out, that was a bug in the meshtastic firmware version that I loaded. Once I updated to the latest firmware, the problem was resolved. These are great little boards that work very well when running meshtastic. I'll probably buy more.

Bit of a learning curve to use the Meshtastic FW but soooo simple to program. Amazing really. I remember the days of direct flashing ROM...now we do it from an online app. The case is flimsy and the antenna is just serviceable but if you are just dipping in your toe this is the set to get. I suggest you print a better case and get a 3000mAh LiPo to make a sweet little unit. Great build quality and perfect soldering. Just be careful and take your time attaching the antenna and battery. The polarity is + on the LEFT. Cheers!

Necesita ser técnico para entender como usarlos, pero funcionan bien.

The Amazon package arrived intact, but the inner package from DIYmall arrived cut open. One antenna was missing, also the protective film on one of cases had been removed. Not sure what happened, perhaps this was a previously returned item. The boards are both Heltec V3 (v3.1) and programmed easily with Meshtastic.
