AcroHub · Flash RSTY-1

Install the latest firmware

v2026.06.30

The RSTY-1 is a classic-ESP32 board, so Chrome/Edge can flash it over USB directly. Plug it in with a data USB-C cable, then:

1Connect the RSTY-1 to this computer with a USB-C data cable (not charge-only).

2Click Install below and pick the USB-Enhanced-SERIAL (CH9102) port.

3Wait ~30 s — the RSTY-1 reboots into the new firmware. Your pairing, score and settings are kept.

Your browser can't flash over USB. Use Chrome or Edge on desktop. This page must be served over HTTPS to flash.

Flashing keeps your saved pairing, Parabird best and settings (stored in a separate NVS area).
If the port doesn't appear, install the CH9102/CH343 driver and replug.
If it stalls, hold the BOOT button while plugging in, then click Install again.
The AcroPro Display (Acrometer) can't be browser-flashed — it updates over USB or BLE-OTA.
