LILYGO T-QTC6 is a cute little IoT controller based on an ESP32-C6 WiFi 6, Bluetooth 5.4 LE, and 802.15.4 wireless microcontroller and a 0.85-inch touchscreen color LCD that can be powered via USB-C or a LiPo battery with the board also supporting charging. The device, sometimes called “T-QT C6” (with a space), also comes with an 8-pin female connector with five GPIOs and a Qwiic connector for UART modules. It’s another addition to the T-QT family with ESP32 wireless microcontrollers and a tiny 0.85-inch display such as the T-QT Pro or the T-QT V1.1. But note that those are development boards, while the T-QTC6 feels more like a complete device.

Seeed Studio Wio Tracker 1110 Dev Kit supports Meshtastic for off-grid communication
The Seeed Studio Wio Tracker 1110 is a dev kit designed to work with the Meshtastic network. The board is built around a Nordic nRF52840 multiprotocol Bluetooth 5.4 SoC and uses the Semtech LR1110 LoRa transceiver for communication. Seeed Studio is selling the Wio Tracker 1110 development board in a bundle with an OLED display and a GNSS receiver, providing everything needed to start experimentation for peer-to-peer LoRa mesh networking. Meshtastic is a free, open-source, decentralized mesh network that uses LoRa radios to establish a low-power, long-range, off-grid communication system in areas without reliable infrastructure. Driven entirely by the community, Meshtastic enables decentralized, encrypted communication without the need for a dedicated router or phone. Previously we have written various versions of the Wio Tracker including the Wio GPS and Wio LTE GPS Tracker. Since Meshtastic projects are becoming popular among developers and enthusiasts, we will likely see many more dev […]
T2-U WiFi and Bluetooth development board supports the Tuya Smart Home framework
The T2-U is a development board compatible with the Tuya Smart Home framework that features a WiFi and Bluetooth module with a 120 MHz RISC processor, some buttons, an LED indicator, GPIOs, power, and a USB-to-serial chip. In 2019, we covered Tuya as a one-stop Smart Home solution allowing companies to easily design and manufacture home automation devices from electronics to the enclosure. For example, the company provides a customizable 4-inch Android touch control panel & Zigbee gateway as well as the Tuya Link SDK allowing customers to further customize the firmware of their Smart Home devices, but I had yet to see a development board compatible with Tuya. T2-U development board specifications: Wireless module – T2-U SoC – Unnamed 32-bit RISC MCU @ 120 MHz with 2 MB flash and 256 KB RAM Wireless Wi-Fi 802.11b, 802.11g, and 802.11n wireless standard.

Remote.It adds Bluetooth assisted WiFi configuration to Raspberry Pi SBC’s
Remote.It, a company providing remote access services, has released an open-source project to enable Raspberry Pi WiFi network configuration using Bluetooth (BLE), so users can easily configure WiFi on the board by simply using their smartphone. Configuring WiFi on a Raspberry Pi usually involves either: Manual configuration – The user connects a monitor and keyboard to the Raspberry Pi to configure the wireless network directly on the device. Pre-configured SD cards, NVMe SSDs, or USB drives – The WiFi ESSID and password can be set in Raspberry Pi USB imager, and the Raspberry Pi will automatically connect to the network at boot time. That’s quick, but less flexible since the credentials can’t be modified after deployment, and it only works when using a single wireless network. Remote.It offers a third option for WiFi provisioning using Bluetooth LE. The Raspberry Pi can run headless or fully enclosed into a product, and […]
