Package Including:
3* ESP32 mini ESP-WROOM-32 Development Board
Features
- This is a powerful Internet of things development board; standalone board mount, stackable on top, or stackable top and bottom.
- Although these D1 Minis have only 16 pins, you're still getting 10 digital I/O and the one A0 analog pin, a reset pin, plus the ground and one 3 volt and one 5 volt pin. This is enough for most projects. After all, you do get the hardware I2C and SPI pins (on D5 through D8).
- This D1 definitely fits on a standard breadboard leaving one open hole available for each pin (on both sides) but being shorter than the 30 pin boards you will have about 6 more rows available for prototyping, especially nice when using the short 460 tie point breadboards.
- 11 digital input / output pins, all pins with interrupt / PWM / I2C / support 1 line (except D0); 1 analog input(3.2V max input). Micro USB connection; Compatible with Arduino; 1MB Flash; 500mA resettable fuse.
- Be aware that the old driver can cause your machine to lock up. If you installed an earlier version of the driver (the one I had had no version number in the file name) search for instructions to remove it.
