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.

HPMicro HPM64G0 – A 1 GHz RISC-V microcontroller

Yesterday, I ended up on the HPMicro website showing the illustration above about a 1 GHz MCU called HPM64G0. It looked interesting enough so I clicked on the link to a page with some documentation for the company’s HPM6700/6400 microcontrollers. But in typical Chinese fashion, I was asked for a mobile phone number to download the documents. No luck this time since a Chinese mobile phone number is required. If anybody can set up a mirror on Mega or other websites easily accessible outside of China that would be appreciated. But eventually, I found an article in Chinese on EETrend where we can learn more about the HPM64G0 which happens to be a 1GHz microcontroller based on the RISC-V architecture. We already had one of those for Arm with the NXP i.MX RT1170, but I had yet to see any RISC-V microcontrollers clocked at such a high frequency. HPMicro HPM64G0 […]
