Not too familiar with that micro. Had to check it out. > ESP32 is a single 2.4 GHz Wi-Fi-and-Bluetooth combo chip designed with the TSMC ultra-low-power 40 nm technology. It is designed to achieve the best power and RF performance, showing robustness, versatility and reliability in a wide variety of applications and power scenarios. • Xtensa® single-/dual-core 32-bit LX6 microprocessor(s), up to 600 MIPS (200 MIPS for ESP32-S0WD/ESP32-U4WDH) • 448 KB ROM • 520 KB SRAM • 16 KB SRAM in RTC • QSPI supports multiple flash/SRAM chips Internal 8 MHz oscillator with calibration • Internal RC oscillator with calibration • External 2 MHz ~ 60 MHz crystal oscillator (40 MHz only for Wi-Fi/BT functionality) • External 32 kHz crystal oscillator for RTC with calibration • Two timer groups, including 2 × 64-bit timers and 1 × main watchdog in each group • One RTC timer • RTC watchdog 34 × programmable GPIOs • 12-bit SAR ADC up to 18 channels • 2 × 8-bit DAC • 10 × touch sensors • 4 × SPI • 2 × I²S • 2 × I²C • 3 × UART • 1 host (SD/eMMC/SDIO) • 1 slave (SDIO/SPI) • Ethernet MAC interface with dedicated DMA and IEEE 1588 support • Two-Wire Automotive Interface (TWAI®, compatible with ISO11898-1) • IR (TX/RX) • Motor PWM • LED PWM up to 16 channels • Hall sensor Secure boot • Flash encryption • 1024-bit OTP, up to 768-bit for customers • Cryptographic hardware acceleration: – AES – Hash (SHA-2) – RSA – ECC – Random Number Generator (RNG) [$1.80 on Digikey](https://www.digikey.com/en/products/detail/espressif-systems/ESP32-D0WD-V3/11657613) They don't seem to have their own IDE, you'll have to either set up the toolchain, build tools, and library yourself or install Eclipse plugin into some capable IDE. That's a slight bummer for those of us spoiled by things like MPLAB or Simplicity Studio or what have you. Just like old times.. From what I can tell, the library is a mixture of C and python, and the C compiler they're using is GNU. Not a bad little uC for the price, has all the stuff you'd expect plus it does WIFI and BT.
