Found this post, but their device is for 868Mhz... The description below is much clear then the wiki of the code V5 https://www.thethingsnetwork.org/forum/t/big-esp32-sx127x-topic-part-1/10247/128 by  CurlyWurly 1) Single Channel Gateway using Heltec WiFi LoRa 32 (with OLED display) Thanks  @Kersing Got the single channel gateway working on my Heltec WiFi LoRa 32 (with OLED display) https://www.aliexpress.com/item/868MHz-915MHz-SX1276-ESP32-LoRa-0-96-Inch-OLED-Display-Bluetooth-WIFI-Lora-Kit-32-Module/32835492243.html?ws_ab_test=searchweb0_0,searchweb201602_1_10152_10065_10151_10344_10068_10130_10345_10324_10342_10547_10325_10343_10340_10341_10548_10192_10541_10190_10084_10083_10307_10301_10303_10539_10312_10059_10313_10314_10184_10534_100031_10604_10603_10103_10605_10594_10596_10142_10107,searchweb201603_25,ppcSwitch_5&algo_expid=2ba45802-8bfd-4728-b9ca-e592aea6c379-19&algo_pvid=2ba45802-8bfd-4728-b9ca-e592aea6c379&rmStoreLevelAB=5 Very nice Just...

you can easily find some good boards from china, but most of them lack of accurate document... Hrere is an example; https://hackaday.io/project/26991-esp32-board-wifi-lora-32 the board looks good with lora and a 128x64 OLED, but the IIC and reset connection is important, since pin can be muxing easily, so every board could be different. pinMode(16,OUTPUT);  digitalWrite(16, LOW); // set GPIO16 low to reset OLED  delay(50);  digitalWrite(16, HIGH); // while OLED is running, must set GPIO16 to high  and, if needed, edit your Wire.begin() to Wire.begin(4,15); (4 = SDA 15 SCL)  i tested it with the Adafruit SSD1306 and the Acrobotics SSD1306 Librarys  both work.  Display size is 128x64 There are discussions on these boards on TＴＮ as a LORA node..or maybee single ch gateway? Heltec has a git :  https://github.com/Heltec-Aaron-Lee And there is another copy call TTGO https://de.aliexpress.com/item/TTGO-LORA32-868-915-Mhz-S...
