ESP-WROOM-32

ESP32 and it’s breakout board ESP-WROOM32 actually impresses me. Expressif surpriced everyone with ESP8288 a few years back, but ESP32 is a serious upgrade. Just look at this list:

  • Supported in Arduino IDE. Straight forward to develope custom solutions.
  • 38 pin IO
  • Dual core 32-bit 240Mhz MCU – 600 DMIPS performance.
  • Floating Point Unit & DSP Instructions
  • 4-16MB Flash
  • 448KB ROM
  • 520KB SRAM
  • 4 x 64 bit timers
  • 3 Watchdog timers
  • RTC
  • Temperature sensor
  • ADC 16 channels 12 bit resolution
  • DAC 2 channel 8 bit resolution
  • 10 channel touch sensor
  • Analogue Pre-Amplifier
  • SD/SDIO/MMC Interface
  • Motor PWM
  • Hall Sensors
  • Led segment output
  • 2xUART
  • CAN
  • 2xI2C
  • I2S
  • Programmable GPIO. Many IO devices can be freely allocated to pins.
  • Infrared Remote controller
  • SPI, Dual, Quad
  • Ethernet
  • Wifi with security
  • Bluetooth
  • Temperature -40 to 85 degrees
  • And much more…

That’s rather good for a breakout measuring 18 x 25.5 mm and costing ca 4.- USD. No wonder why the internet community have embrased it. And yes – I have ordered some. You should too!
