LilyGO has recently released the T-Display S3 Pro LR1121, a new ESP32-S3 development kit with a Semtech LR1121 transceiver for universal LoRa connectivity across the sub-GHz and 2.4GHz bands. The board is an update to the earlier T-Display S3 Pro, which features a slimmer design and a 2.33-inch touchscreen display, but this new LR1121 variant adds sub-GHz and 2.4 GHz LoRa/(G)FSK support along with a voice communication kit that includes a MAX98357A I2S speaker amplifier, a PDM/I2S digital microphone, vibration motor, and a RTC. There are also programmable buttons, Qwiic connectors, and a 1/4-inch tripod mount, as well as a 2000 mAh Li-ion battery, USB-C for power, and ultra-low sleep current. These features make it suitable for applications such as LoRa walkie-talkies, Meshtastic nodes, voice-enabled IoT devices, portable dashboards, and experimental long-range wireless systems.
