Holtek VFD DEMO KIT User Manual
The VFD DEMO KIT is a development board from Holtek that uses the HT49CVX VFD MCU series to drive VFD panels directly, without extra driver chips. It includes a keypad display, infrared remote receiver, A/D conversion and temperature measurement functions.
The board can operate in three ways – MCU mode, HT49CVX mother‑board + ROM‑LESS mode, and emulator mode – each with its own jumper settings and power configuration. A built‑in voltage doubler converts a 9 V DC input to –30 V for the VFD and +5 V for the MCU, and the infrared remote mirrors the keypad functions for clock setting, media selection, playback control, dimming and sensor read‑outs. This manual is written in Chinese.
