General issue report
I want to read analog data from the sensor, what history should I use to ensure that other features work?
Hi @isthaison, you can use pins as shown below to read analog data. Please check the "NOTE" to know their limitations.
If so, then in this situation only IO4 pin can be used. no can't use S3's SPI and LED, right?, or is there another way
If so, then only IO4 and IO19 can be used on this board. but it is used for LED and USB, which is quite inconvenient. If there is an upgrade board, we can always design at least 2 pins for ADC and 2 Digital pins. This will make it easier for developers to develop their own integrations
You are right. This ESP-S3 development board has a shortage of IO pins due to the integration of RGB screen, audio input, and output functions. The upcoming ESP-P4 development board will provide ample IO pins.
When will the ESP-P4 development board be released? Because I am preparing to deploy the project, in large quantities
I'm sorry, but there is currently no exact time available.
Edited: About 1-2 months later.
I'm sorry for not getting back to you sooner. You can contact Espressif's business team to get a sample.
Can I ask for design files (dfx, etc). some format that can be imported into design. instead of the dpf file that the document provides. I am designing an expansion pcb part to connect the expansion pin
If so, I have to redraw. but it will have the risk of errors between related departments
