L-ILY&G//O® TTGO Meshtastic T-Beam V1.1 ESP32

L-ILY&G//O® TTGO Meshtastic T-Beam V1.1 ESP32 433/868/915/923Mhz WiFi BLE Lora Development Board, ESP-32 Paxcounter Module SMA Metering Passenger Flows (915MHZ OLED)

• MCU: Onboard ESP32 MCU with WiFi Ble [v4.2] transmission function, 4MB flash and 8MB PSRAM, supports daily programming at entry level
• GPS: GPS NEO-6M module, with RCT watch battery and mini ceramic antenna for daily position determination
• Antenna: Use 3D WiFi antenna to save space, we also reserved IPEX antenna base for use. [Note that the built-in antenna and external antenna cannot be used together
• Programming chip: the CH9102 programming chip with serial interface is suitable for daily programming. Before connecting it, you need to make sure the driver is installed on the computer.
