Built on the Nordic nRF52840 MCU and the SX1262 LoRa chip, this second-generation board features a 6-layer PCB with immersion gold process for superior signal integrity and reliability. Available in multiple configurations, including GNSS, Screen, and Soft Antenna options. Rev 2.0 Upgrades and Core Features Enhanced Stability (Rev 2.0): Upgraded from 4 to 6 PCB layers with immersion gold process, providing a more complete RF ground and superior signal transmission quality. Ultra-Low Power: Achieves a minimal 11 µA in deep sleep consumption, maximizing field deployment and battery life. Positioning Ready: Supports GNSS and GPS module integration (available as an option) via a dedicated 1.25x8P connector for precise location tracking. Dual Wireless: Features LoRa (SX1262) for long-range mesh networking and Bluetooth LE 5 (nRF52840) for local connectivity. Flexible Power Inputs: Integrates charging circuits for LiPo battery, Type-C USB, and Solar Panel via dedicated 1.25x2P connectors. Technical Specifications Summary Model: Mesh Node T114 V2 (Rev 2.0) MCU: nRF52840 (1M ROM, 256KB SRAM) LoRa Chip: SX1262 | Frequency Options: 863-870MHz / 902-928MHz Bluetooth: BLE 5, Bluetooth mesh Max. Sensitivity: -135dBm@SF12 BW=125KHz Display (Optional): 1.14 inch TFT-LCD display Dimensions: 50.80 x 22.86mm ⚙️ Click for Full Hardware & Customization Details The T114 Rev 2.0 includes extensive hardware resources, including 4 x SPI, 2 x TWI, 2 x UART, 4 x PWM, QPSI, I2S, PDM, QDEC, and more.
