Description

STM32-FT01 – E-Paper Adapter Board with Front Light, Touch

STM32-FT01 is a compact, all-in-one adapter board designed for SPI e-paper displays. It integrates front light, touch panel support, and micro SD storage, while seamlessly working with Raspberry Pi and DESPI-M02L mainboards. Built-in DIP-switch resistor matching ensures optimal display performance with various driver ICs. Multiple interface options, flexible form factor, and included Keil4 example code make development fast and hassle-free.

Technology Highlights

Driver IC Compatibility

Instant RESE matching via DIP switch selects boost reference resistor – 0.47Ω (UltraChip) or 2.2Ω (Solomon & four‑color). No PCB rework needed.

①

0.47Ω – UltraChip (UC) series driver ICs

②

2.2Ω – Solomon (SSD) series driver ICs

③

2.2Ω – Four‑color (B/W/R/Y) e‑paper displays

Boost & Front Light

Pre‑validated boost circuit with test points (PREVGH/PREVGL). Multi‑voltage front light support (3.3V ↔ 9‑21V) with continuous dimming.

①

P2: 3.3V ↔ 9‑21V selection

②

SS1: 9/12/15/21V voltage steps

③

R14: continuous front‑light dimming

Dual‑Platform Plug‑in

Direct connection to Raspberry Pi (P1, rear) and DESPI‑M02L mainboard (P8‑P10, rear). Prototype on Pi, develop on STM32 – one board, two workflows.

①

Raspberry Pi 40‑pin direct plug‑in

②

DESPI‑M02L mainboard interface (P8‑P10)

③

Clean stacking with rear‑side connectors

Touch Panel Support

Dual touch interfaces for ≤2.9″ (P6) and ≥3.7″ (P7). Supports touch panels up to 7.5 inches, with reverse insertion for 2.9″ and 7.5″ models.

①

P6 – for touch panels ≤2.9″

②

P7 – for touch panels ≥3.7″

③

Physically isolated from front‑light to prevent misinsertion

EPD FPC & Waveform OTP

24‑pin, 0.5mm pitch FPC connector (P5) with display‑side‑up insertion. Waveforms pre‑burned into OTP – call built‑in fast/partial refresh without LUT tuning.

①

Supports all SPI e‑paper displays up to 13.3″

②

Pre‑stored waveforms for instant refresh

③

Fast / partial update support

Development Ecosystem

Complete Keil4 example code, full documentation, and test points for debugging. 58.6 × 54.7 mm compact size, 3.3V logic (front light 5V).

①

Keil4 example projects with image data

②

PREVGH/PREVGL test points for boost verification

③

18 years EPD expertise – validate in days
