## What Seeed actually sells
|
|||
|
|
|
|||
|
|
Seeed's strategy is a small family of **driver boards** that pair a XIAO
|
|||
|
|
MCU (RP2040 / ESP32-S3 / ESP32-C3) with a generic e-paper FPC connector,
|
|||
|
|
plus a la carte **panels**. The user-cited 13.3" Spectra 6 is the largest
|
|||
|
|
panel in this family.
|
|||

## Velxio shortlist (Phase 1)
|
|||
|
|
|
|||
|
|
To cover most user demand without exploding scope, the first emulator drop
|
|||
|
|
should support these 5 representative panels:
|
|||
|
|
|
|||
|
|
| Velxio metadata id | Panel | Resolution | Colours | Controller IC | Notes |
|
|||
|
|
|---|---|---|---|---|---|
|
|||
|
|
| `epaper-1in54-bw` | 1.54" 200×200 | 200×200 | B/W | SSD1681 | Smallest, simplest, fast init |
|
|||
|
|
| `epaper-2in13-bw` | 2.13" 250×122 | 250×122 | B/W | SSD1675A / IL3897 | Classic ESP-NOW badge |
|
|||
|
|
| `epaper-2in9-bw` | 2.9" 296×128 | 296×128 | B/W | SSD1680 | Common in retail tags |
|
|||
|
|
| `epaper-4in2-bw` | 4.2" 400×300 | 400×300 | B/W | UC8176 / SSD1683 | Mid-size, partial update |
|
|||
|
|
| `epaper-7in5-bw` | 7.5" 800×480 | 800×480 | B/W | UC8179 / GD7965 | Largest mono |
|
|||
|
|
|
|||
|
|
Phase 2 colour panels:
|
|||
|
|
|
|||
|
|
| Velxio metadata id | Panel | Resolution | Colours | Controller IC |
|
|||
|
|
|---|---|---|---|---|
|
|||
|
|
| `epaper-2in13-bwr` | 2.13" tri-colour | 250×122 | B/W/Red | SSD1680 |
|
|||
|
|
| `epaper-5in65-7c` | 5.65" 7-colour ACeP | 600×448 | 7 (ACeP) | UC8159c |
|
|||
|
|
| `epaper-13in3-spectra6` | 13.3" Spectra 6 (Seeed 6569) | 1200×1600 | 6 | EPD13in3E (Spectra 6 controller) |
|
|||
|
|
|
|||
|
|
## What about IT8951?
|
|||
|
|
|
|||
|
|
The **6"–10.3" Carta panels** (EE03) use Waveshare's IT8951 driver HAT,
|
|||
|
|
which exposes a serial protocol over SPI/USB rather than raw waveform
|
|||
|
|
control. Different beast — defer to Phase 3.
