Pin-Out and Pin-Muxing¶

The MitySOM-335x TiWi-BLE based module requires that a number of additional pins be used on the module to support the WiFi and Bluetooth radios.

Pin-Out and Pin-Mux Spreadsheet¶

This spreadsheet shows the complete MitySOM-335x WiFi/BLE 204-pin connector pin-out. Typcially this is used to assist in developing a potential pin-mux solution for a design based on the MitySOM-335x WiFi/BLE module.

Note that as a complimentary service to our MitySOM-335x customers we are happy to have one of our application engineers complete a version of this spreadsheet using the specific peripherals that you require for your custom design. Please contact your Critical Link account representative for details about this program.
