Anyway, I don’t understand it at all, because, after compiling the entire program, it is indicated that the sketch takes up 11% of RAM and 62% of ROM. I use platformIO. ESP32 module board with 4MiB pSRAM created by Espressif. FCC part 15.247 tested (FCC ID 2AC7Z-ESP32WROVER). Uses 40MHz crystal oscillator. Does not include U.FL connector. Based on ESP32-D0WDQ6 chip. Since June 2018, new modules have been upgraded to 8MiB pSRAM.
ADC and DAC pins are predefined and you have to use the manufacturer specified pins. But other functions like PWM, SPI, UART, I 2C etc. can be assigned to any GPIO pin through program.

Ultimately, I got the correct firmware and Flip running, but it could not see my board. However, I eventually explored the Flip software, which even has an ‘Emulate Mode’ built in and risked tried known working Arduino UNOs and other Mega 2560 R3s, but they were not seen by the Flip software either. Let us start exploring the ESP32 Pinout by taking a look at the ESP WROOM 32 Pinout. The following image show the pinout of a typical ESP-WROOM-32 Module. It consists of 38-pin (14 pins on each long edge and 10 on bottom short edge). Getting Started with VS Code IDE - ESP32 - — ESP-IDF Programming Guide latest documentation". docs.espressif.com .

Module has a ceramic antenna and an U.FL antenna connector. This module has a different footprint than the ESP-WROOM-32/ESP-32S modules. Discontinued. Limited distribution, pre-production module created by Espressif for beta testing purposes; this module used the ESP31B, the beta testing chip for the ESP32 series.

[27] The ESP32 LED PWM controller has 16 independent channels that can be configured to generate PWM signals with different properties. All pins that can act as outputs can be used as PWM pins (GPIOs 34 to 39 can’t generate PWM). LOLIN32 Lite (Retired) [WEMOS Electronics]". wiki.wemos.cc. Archived from the original on 2018-11-14 .

It is very helpful in actual work that the module has more pins and a wider range of power voltages, as well as the ability to support Bluetooth and show higher performance.LOLIN32 Pro (Retired) [WEMOS Electronics]". wiki.wemos.cc.

Variation of ESP32-WROVER-E module configured to use an on-board U.FL compatible connector. PCB trace antenna not connected by default. Extra hardware features. There are ESP32 development boards with extra hardware features. For example, some may come with a built-in OLED display, a LoRa module, a SIM800 module (for GSM and GPRS), a battery holder, a camera, or others.

what are the steps that the arduino-IDE-developers have to take until the ESP32-support reaches the stage as described in the following: ESP32 has 16 RTC GPIOs, which are part of the RTC Low-Power subsystem. These pins can be used to wake ESP32 from deep sleep as external wake-up source. ADC The ESP32 adds an extra CPU core, faster Wi-Fi, more GPIOs, and supports Bluetooth 4.2 and Bluetooth low energy. Additionally, the ESP32 comes with touch-sensitive pinsthat can be used to wake up the ESP32 from deep sleep, and built-in hall effect sensor.
