Seeed SenseCAP Indicator

The Seeed SenseCAP Indicator is a 4" square desk display: a 480×480 IPS color touch LCD driven by an ESP32-S3 with 8 MB of flash and 8 MB of PSRAM, with an RP2040 beside it for the sensors, the buzzer and the microSD slot. It comes as the D1, D1S, D1L and D1Pro, which differ in their sensors and radios; FrameOS uses the S3's half, which is the same on all four.

It's the first LCD the FrameOS ESP32 firmware drives (2026.10.21+), and it changes what a microcontroller frame can do: scenes animate, interfaces answer a tap, and nothing waits half a minute for e-paper to refresh.

What it does

Pick the Seeed SenseCAP Indicator D1/D1S hardware preset (seeed_sensecap_indicator_d1) and:

• Scenes animate. A scene whose render interval is under a second renders back to back, with the scene drawn straight into the LCD's frame buffer and only the part that changed redrawn: the store's DVD Logo Bounce runs at about 20 frames a second, its Ken Burns photo slideshow at 7-8.
• Touch works like a Pi touchscreen: taps, double taps, long presses, swipes and pointer events reach scenes (input events). Interfaces built with JSX and Tailwind classes - a home panel's switches, a calculator, a player - answer a tap in a fraction of a second.
• The button and the edges come bound to the frame (button actions): press the top button to turn the screen off or on, press it twice for the next scene, hold it for the previous one, and swipe in from the right or left edge for the next or previous scene. A touch on a dark screen only wakes it.
• It boots to the FrameOS mark, with a line saying what it's waiting for - Connecting to Wi-Fi, Updating firmware, Starting - and shows a picture as soon as WiFi is up.

What it doesn't

• The microSD slot, the buzzer and the sensors belong to the RP2040, which the S3 only talks to over a serial line, so FrameOS doesn't drive them (nor the LoRa radio of the D1L and D1Pro). Assets live in 1 MB of the S3's own flash instead: room for a handful of photos, with file names of 28 characters at most.
• No battery. It runs on USB power, so there's no deep sleep, and scene state that changes is written to flash every ten minutes rather than every minute - a flash write disturbs the picture for a frame.

Setup

1. In the FrameOS backend or FrameOS Cloud, create a frame with Flash embedded device.
2. Choose ESP32-S3, select the Seeed SenseCAP Indicator D1/D1S preset, and enter your WiFi details.
3. Flash it over USB from the browser - the backend writes the release image for the board and sets it up as this frame.
4. Install scenes as usual - they sync over WiFi, and the device updates itself over the air. DVD Logo Bounce, Touch test and Ken Burns from the scene store are a good first look at what the screen can do.

Status

🟢 Confirmed working - tested on real hardware (a D1S): the picture the right way round, taps landing under the finger, the button and edge swipes switching scenes, and a steady picture while it animates.
