⚡ GUITION rotary encoder gets ESP32-S31 upgrade

GUITION has updated its JC3636F118C-I-YR1 rotary encoder with a 1.8-inch touchscreen display to feature the new ESP32-S31NRV16 SoC. This module replaces the previous ESP32-S3 model, integrating WiFi 6, Bluetooth 5.4, and 802.15.4 connectivity in a compact form factor. The device targets developers needing a combined input and output interface for embedded projects.

The core component is the ESP32-S31NRV16, which includes a RISC-V high-performance CPU running at 320 MHz with FPU and SIMD support, alongside a low-power MCU core. Memory resources consist of 512 KB SRAM, 32 KB low-power SRAM, and 16 MB of PSRAM. Wireless capabilities cover 2.4 GHz WiFi 6, Bluetooth 5.4 with LE Audio and Mesh support, and 802.15.4 radio for Zigbee, Thread, and Matter protocols.

Physical features include a 16 MB SPI flash, a MicroSD card slot for configuration or media playback, a speaker, and a microphone. An optional rechargeable battery is also available. The 1.8-inch display serves as the primary visual interface, while the rotary knob provides tactile control. This update aligns the hardware with newer Espressif silicon standards.
