Flash a Tree

One-click installer for the Orchard Tree firmware. Plug an ESP32 into your computer, click Connect, pick the serial port, and the latest signed firmware flashes in about 30 seconds.

1 · Plug in your Tree

USB cable from your computer to the ESP32 board.
Confirm a new serial port shows up (COM4 on Windows, /dev/cu.SLAB_USBtoUART on macOS, /dev/ttyUSB0 on Linux).
If you don't see a port, install the CP210x USB-UART driver (Windows only — macOS and Linux ship it).

2 · Click Install, pick your board

When you click the button below, your browser opens a small dialog listing every serial port on your machine — pick the one labeled Silicon Labs CP210x (Windows) or cu.SLAB_USBtoUART (macOS) or ttyUSB0 (Linux). If you have several boards plugged in, they all appear here so you can choose which one to flash.

From there the installer will:

Erase the board's existing firmware.
Write a fresh Orchard Tree firmware image (~1 MB, version 0.4.9).
Reboot the board into the Orchard runtime.

Your browser doesn't support Web Serial. Open this page in Chrome, Edge, Brave, or Opera on a desktop computer. Web Serial needs a secure context. Reload this page over https:// or http://localhost.

Requires a Chromium-based browser (Chrome / Edge / Brave / Opera). Firefox and Safari don't expose the Web Serial API yet. Close any other program holding the port (PlatformIO monitor, Arduino IDE, PuTTY) before clicking — Windows lets only one process own a COM port at a time.

3 · Claim your Tree

When the flash finishes, the board reboots and shows a claim code. Head to the claim page, connect your Chia wallet (Sage or Goby), prove your Orchard Pass, and enter the code — your Tree is bound to you and starts reporting.

First connect your WiFi too: point the Tree at your network during setup so it can reach the oracle. New here? The Operator Quickstart walks through the whole flow.

What this firmware does

Self-detects the connected sensors (MQ-135, BME280, NEO-6M GPS — others over time).
Stores a per-device node id and HMAC signing secret in NVS on first boot.
Connects to WiFi using credentials you push during provisioning.
POSTs a signed sensor sample to your Oracle every 60 seconds.
Accepts OTA firmware updates from the dashboard on port 80.
