ESP32-DevKitM-1 is a ESP32 MINI-1(1U) based development board manufactured by Espressif.
Most I/O pins are split between the headers on both sides to facilitate connection.
Users can connect peripheral devices with either jumper wires or mount ESP32-DevKitM-1 on a breadboard.
OverviewThis is a small and practical development board with the following features:- ESP32-MINI-1, or ESP32-MINI-1U module- USB serial programming interface, which also ensures the power supply of the board- Headers- Push buttons for reset and activation of the firmware download mode- a few other componentsInterfacesBuilt-in moduleESP32-MINI-1 module or ESP32-MINI-1U module.
ESP32-MINI-1 comes with an integrated PCB antenna.
ESP32-MINI-1U comes with an external antenna connector.
The two modules both have a 4 MB flash in the chip housing.
