THE CORE

Built around
ESP32-S3.

The WROOM-1-N16R8 module packs 16 MB of flash and 8 MB of PSRAM onto a single, certifiable footprint. Wi-Fi 2.4 GHz and Bluetooth LE 5.0 are built in — no external antenna, no extra chips, no surprises at assembly.

Designed for Rust or C firmware targeting Solana signing, IoT telemetry, and secure BLE peripherals — straight out of the box.

SECURE ELEMENT

Keys that never
leave silicon.

The NXP SE050 secure element moves cryptographic operations off-chip into tamper-resistant hardware. Private keys are generated and stored inside the element — they are never exposed to the application processor, not during signing, not ever.

Purpose-built for Solana transaction signing, hardware wallets, and applications where key compromise is simply not an option.

PERIPHERALS

Everything wired up.
Already documented.

Display, touch, camera, audio, storage — all connected and referenced in the public hardware package. Ship the feature, not the breakout board.

01

Display + Touch

LCD flex connector with TSC2007IPWR capacitive touch controller on shared I2C bus.

02

Camera

Dedicated connector for image capture and computer vision, pinout-ready for standard OV modules.

03

Audio I/O

ES7243E ADC, NS4168 power amplifier, and dual onboard MEMS microphones for voice applications.

04

microSD

TF1 socket for data logging, firmware assets, and SPIFFS-compatible local storage.

05

USB Type-C

Native USB FS on GPIO19 and GPIO20. No CP2102. No FTDI. Direct chip access, zero latency penalty.

06

Expansion I/O

Direct GPIO breakout, shared I2C bus, and XL9535-backed IO2/IO3 headers for external peripherals.

ONBOARD SENSORS

Built-in awareness.
No extra boards.

Three sensors ship on the board itself — temperature and humidity, ambient light, and a 3-axis accelerometer. Enough context-awareness to build responsive applications without stacking breakout boards.

All three share the onboard I2C bus, leaving your expansion headers free for whatever the project demands.
