License: CC-BY-SA 3.0
Homely WSN Basic Board (V1) is an IoT board to collect environmental data (temperature, humidity and pressure) and to push them to a centralized server through Wi-Fi.
The entire board is manually assemblable, no stencil is required. Hot air gun will be necessary for BMP280 and SHT30.
You need an external USB-serial converter to upload the firmware. You may use this, designed to be pin-compatible with this board.
The firmware will be published on Github, but it still requires a bit of work.
After flashing firmware, you need you solder the SJ2 to enable deep-sleep.
Each manufactured board must have a version. Version advancements are ruled accordingly to Semantic Versioning, similarly to what usually happens in software development.
To quickly identify the status of each version, I use emojis. The following list explains their meaning:
