[CNX-Software] - ESP32 board with rotary encoder gets 2-key keypad shield

LILYGO TTGO T-Encoder, a round-shaped ESP32 board with a built-in rotary encoder, has gotten a shield with a 2-key keypad based on WCH CH552 8-bit microcontroller. Launched several months ago, the TTGO T-Encoder is a USB-powered rotary encoder with ESP32 microcontroller offering WiFi and Bluetooth connectivity, and now, you can build a keypad with rotary encoder thanks to T-Encoder shield that features two mechanical switches and keycaps with RGB LED backlight.   Since we missed it at launch, let’s check out the tiny TTGO T-Encoder board specifications first: System-in-Package (SiP) – Espressif ESP32-PICO-V3-02 with MCU – ESP32 Xtensa dual-core 32-bit Xtensa LX6 microcontroller up to 240 MHz, 448 KB ROM for booting and core functions, 520 KB SRAM for data and instructions, 2.4 GHz WiFi 4 and Bluetooth 4.2 BR/EDR + LE connectivity Memory – 2MB SPI PSRAM Storage – 8MB SPI flash Dimensions – 7×7 mm Antenna – Ceramic [...]
