NRF7002EB and External Device Compatibility

Hi Jon,

Could you share how you previously connected the I2C display? You might find additional available pins or use fly wires for the I2C connection.

Best regards,

Charlie

Thank you Charlie!

Further question, since the external board connector on the Thingy53 is a hardware component, is there a hardware change required? Or does changing the GPIO in the devicetree section of the VS code extension route the proper pins to the connector?

Thank you!

Jon

Hi Jon,

Thanks for reaching us for this issue.

Looking in to PCB edge connector and zephyr\boards\nordic\thingy53\thingy53_nrf5340_common.dtsi:

edge_connector: connector {

compatible = "nordic-thingy53-edge-connector";

#gpio-cells = <2>;

gpio-map-mask = <0xffffffff 0xffffffc0>;

gpio-map-pass-thru = <0 0x3f>;

gpio-map = <8 0 &gpio0 5 0>, /* P8, P0.05/AIN1 */

<9 0 &gpio0 4 0>, /* P9, P0.04/AIN0 */

<15 0 &gpio0 8 0>, /* P15, P0.08/TRACEDATA3 */

<16 0 &gpio0 9 0>, /* P16, P0.09/TRACEDATA2 */

<17 0 &gpio0 10 0>, /* P17, P0.10/TRACEDATA1 */

<18 0 &gpio0 11 0>, /* P18, P0.11/TRACEDATA0 */

<19 0 &gpio0 12 0>; /* P19, P0.12/TRACECLK */

};

GPIO0 4 and 5 are already be used, you may check other avaliable GPIO pins for I2C by checking How to work with Devicetree Visual Editor I provide by nRF Connect for VS code extension.

Best regards,

Charlie
