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.
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.
For detailed technical information about the components of the Robin module and the COM Express™ standard, please refer to the documents listed below.
Guidelines for designing a COM Express™ carrier board:
Important: Do not use a zero delay buffer for the LPC Clock. If your design has more than one LPC Clock sink, use a normal clock buffer instead.
