You'll be notified about news and stock updates for this project.

Espoir is a fully compliant Power over Ethernet+ (PoE+ 802.3af/at) ESP32-based devboard that lets you jump straight to business. It provides up to 15 Watts of power to your application at 5 V and 3.3 V. Four full copper layers give the board enhanced electromagnetic compatibility and thermal dissipation. Its PI-filtered power input and outputs give excellent analog performance. Finally, its modern USB-C connector helps get rid of old standards.

Espoir brings versatility to your projects. Enjoy its high connectivity with 16 IOs, Wi-Fi, Bluetooth, USB-C and 100Base-T Ethernet. Its form factor and mikroBUS™ header easily accommodate over a thousand existing add-on boards. The best part? It is designed exclusively with free, open source software and is certified open source by the Open Source Hardware Association (OSHWA).

From Smart Gardening to Complete Home Automation

Espoir stems from a market-gardening automation project. As such, it is designed with outdoor use in mind and handles servomotors, relays, valves, and all kinds of sensors. Use it to turn "dumb" devices smart and complete your home automation. Turn it into a Wi-Fi access point to extend your network. Use Espoir for smart lighting, access control and motion detection, assembly line tracking and item scanning. Espoir’s ESP32 can also handle audio applications.
