ESP32-PICO-D4 UART, SPI and I2C

I need to use 2 UARTS, 1 SPI and 1 I2C in a particular application featuring the ESP32-PICO-D4. I'm currently designing the PCB and was looking for confirmation from the community if the pins I've chosen are correct and there won't be any conflicts while programming the part. For SPI i've chosen VSP...

Re: Esp32-PICO-D4 Antenna Matching circuit

There's no "correct", a matching network needs to be tuned for each particular PCB design and so will vary between them. The first schematic has a placeholder (don't pay too much attention to the values or symbols, they will share the same footprint and so any of those positions may be populated wi...

Esp32-PICO-D4 Antenna Matching circuit

In the ESP32-PICO-D4 datasheet the matching network is shown like the first image which shows a C, L, C network, whereas the matching network in the ESP32-PICO-KIT-V4.1 schematic shows a matching network like the second image which shows a L, C, C network. Which one of these is correct?
