Re: ESP32-C3 max speed?

Hi g4km4n, SDIO should be the fastest option but ESP32-C3 does not have SDIO peripheral.

More information:

Re: Should the reset (EN) pin have an RC circuit?

Hi IamDikoy,

RC circuit at CHIP_PU pin is indeed recommended. Check the Section "2.2.1 Power-on Sequence" in ESP32 Hardware Design Guidelines.

I am getting surprised with GitHub Copilot's performance. It is fun to use and a good brain exercise. My experiences are pretty much similar to what is presented in https://www.youtube.com/watch?v=RDd71IUIgpg

The application is a piece of art. Like PCB art but for code.
I like your approach to inline documentation. I feel like reading a novel.
Getting ChatGPT to do the presets is the cherry on top.

Re: ESP32-S2-DevKitM-1 vs ESP32-S2-DevKitC-1R

Hi n47h4n, The boards have a different on-board module and PSRAM size. For detailed comparison see: - ESP32-S2-DevKitM - https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/hw-reference/esp32s2/user-guide-devkitm-1-v1.html#ordering-information - ESP32-S2-DevKitC - https://docs.espressif.co...

Re: Question about ULP processor

Hi PeteDD, In the meantime, the RISC-V version of ULP was introduced in the new ESP chip series and several new examples have been added. Here are the links: - ULP-FSM: https://github.com/espressif/esp-idf/tree/d29e53dc0c59d1b1b01c5e2c3ca1b22113828587/examples/system/ulp_fsm - ULP-RISC-V: https://gi...

Re: ESP32-C3-wroom vs ESP8685-wroom

Hi ClaudioCnd, ESP8685 chips have flash inside the chip package and smaller number of pins exposed so the chip package and the modules are smaller compared to ESP32-C3 modules. There are couple of ESP8685-WROOM module variants and for exact details and comparison I would suggest checking the Product...

What is the input capacitance of the ESP32 internal Pierce oscillator?
Hi @memory_stick,
The capacitance of pins is provided in the chip datasheet. Below is the value from ESP32 Series Datasheet v3.8

Re: Does the ESP32 have SIMD-like instructions?

Hello!
Because of several requests, the Processor Instruction Extension (PIE) chapter of ESP32-S3 Technical Reference Manual has been prioritized and now is scheduled for publishing on 8 September 2022.

Re: ESP32-DevKitM-1 Development Board is a single or a dual core board?

Hi ALGONSI, ESP32-U4WDH chip variant installed inside ESP32-MINI-1 module has been upgraded from single to dual-core in December 2021. This information is covered in ESP32 Datasheet on page 52 in the footnote. After that date, newly manufactured ESP32-MINI-1 modules and then ESP32-DevKitM-1 boards s...
