Re: PSRAM/SD card/PICO D4
Hi,
For your reference, CS# is tied to either SD2 or SD3, and a 10k pull-up is necessary. Thanks.

Re: Looking for a ESP32‑D2WD module
Hi,
I'm afraid there is no such ESP32 module. Further sales questions can be sent to https://www.espressif.com/en/company/co ... stions-crm. Thanks.

Re: New Wroom-32 modules JTAG Problem
It seems like the initial firmware is interfering with JTAG pins.
Do you know what is the firmware flashed onto these new modules at factory, and why does it use JTAG pins?

Re: PSRAM/SD card/PICO D4
Hi,
You may try the following connection:
PICO <----> PSRAM
SD1 <----> SIO0
SD0 <----> SIO2
CLK <----> SCLK
CMD <----> SIO3
IO17 <----> SIO1
SD2/SD3 <----> CS#
Hope it'd help. Let me know if you have further questions. Thanks.

Re: Guidelines for external antenna layout
Hi I want to know how to connect an external antenna with an ESP32-wroom-32 as we have an application of light bulb in which the ESP32 module will go inside the aluminium body of the bulb. This will decrease the range/signal strength of the WiFi and BLE. So is it possible to solder an external on t...

Re: Document Requests
Documentation of functions implemented in ROM would be also nice. Technical reference manual also does not correspond with ESP-IDF (many registers / register bits are missing). E. g.: DPORT_APP_CACHE_CTRL1_REG is missing (it is according to ESP-IDF very important to work around a hardware bug how t...

Re: Document Requests
Is there any written protocol specification for developing an ESP-TOUCH client? The documentation here https://www.espressif.com/en/products/software/esp-touch/resources talks a bit about how it works at a very high level, and the API for the ESP32 and ESP8266, but there's nothing really describing...
