The Heltec Wifi LoRa V1 was released in 2017, It has ESP32 (Wi-Fi, BLE), SX127x (LoRa radio), a Li-Po battery management system and 0.96” OLED. You still can build and flash MeshCore on it.

The first time you flashed your RAKwireless based MeshCore repeater you probably connected its USB-C port to your PC and used the web based MeshCore flasher. But now your repeater is 12m up in the air? No worries, you can use the OTA feature to upgrade the firmware over bluetooth whilst sitting in a comfortable chair!
