Hello,
I'd like to use ESP32-PICO-D4 in my motorcycle data-logger module.
First of all - do i need anything more that things in "peripheral schematics" in datasheet to run module?
Secondly - 5 meters of wifi range is more than enough for me, then do i need to make matching circuit (L5, C27, C28) for wifi antena? Or can I just connect antena directly to PICO's pin and ground? What is cheap and popular antena i can get?
Do i need capacitors between SENSOR VP and CP, CN and VN?
Regards

1. To simply run the module, "peripheral schematics" is enough.
2. You can solder a 0R resistor in L5, leave C27 and C28 unsoldered and see if RF performance is acceptable.
3. You can use the PCB antenna same as the one in our reference design: https://www.espressif.com/sites/default ... n_V1.0.zip
4. No, you don't need to add caps between SVP and SCP, SVN and SCN, unless you want to use the LNA ADC.
Thanks.
