Carrier Board (Woodpecker, Robin)

Since Woodpecker and Robin are COM Express Modules, it is necessarily to have a carrier board where the needed connectors are placed, power supply is done. etc.

Toradex Carrier boards

• Lily, A version for Robin and one for Woodpecker available.
• Daisy, A Pico-ITX (100x72mm) form factor baseboard for Robin.

Developing a carrier board

For most of the applications developing a specific carrier board is necessary. Toradex provides reference schematic in order to ease development and reduce the risk. Toradex may also develop carrier boards for customers.
