LILYGO T-QT Pro 0.85-inch WiFi IoT display adds support for battery charging

LILYGO T-QT Pro is an ESP32-S3 WiFi and BLE IoT board with a 0.85-inch color display, 4MB flash, 2MB PSRAM, a USB-C port, a few GPIOs, and support for LiPo battery with charging. It is an upgrade to the ESP32-S3-based LILYGO T-QT V1.1 board that also supports LiPo battery power but lacks a charging circuit, so you had to remove the battery and charge it manually each time. The T-QT Pro adds a charging circuit and switches from an ESP32-S3 with an 8MB flash design to one using ESP32-S3FN4R2 with 4MB flash and 2MB PSRAM. LilyGO T-QT Pro specifications: Wireless MCU – Espressif Systems ESP32-S3FN4R2 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 4MB flash, 2MB PSRAM, wireless connectivity Connectivity via ESP32-S3 2.4 GHz 802.11 b/g/n Wi-Fi 4 with 40 MHz bandwidth support Bluetooth Low Energy (BLE) 5.0 connectivity with long-range support, […]

Year 2022 in review – Top 10 posts and statistics

It’s the last day of the year and the time to look at some of the highlights of 2022, some traffic statistics from CNX Software website, and speculate on what 2023 may bring us. The semiconductors shortage continued in 2022, but things are looking brighter in 2023 with the full reopening of the world mixed with forecasts of difficult economic times that should keep the demand/supply equation in check. On the Arm processor front the biggest news of the year, at least in this corner of the Internet, was the launch of the Rockchip RK3588 octa-core Cortex-A76/A55 processor together with interesting single board computers that we’ll discuss below. Announced last year, the Amlogic A311D2 octa-core Cortex-A73/A53 was finally made available in a few SBC’s, and we finally got some news about the Amlogic S928X Cortex-A76/A55 SoC showcased in 8K TV boxes, but we have yet to see it in action.
