The stamp hole design also makes it able to be easily embedded in your PCB, greatly saving your costs and time to build and test a prototype. Note: FireBeetle 2 and FireBeetle pins and sizes are not compatible, and neither are the expansion boards. This guide provides a comprehensive overview of downloading and configuring the Arduino IDE for the FireBeetle 2 ESP32-E board, including essential steps for SDK installation and board selection, along with tutorials for basic and... This article explains how to manually install the CH340 driver for the FireBeetle 2 ESP32-E in case it is not automatically installed on Windows or MAC. FireBeetle 2 ESP32-E(N16R2) has up to 21 physical GPIOs, which are mainly for connecting peripherals like sensors, actuators, etc.

Meanwhile, these IO pins can be multiplexed for other functions such as UART, SPI, I2C and so on. The table below provides users with a detailed description of FireBeetle 2 ESP32-E(N16R2) GPIO. It is recommended not to multiplex the pin IO0/D5, IO1/TXD and IO3/RX since they will be occupied when using USB-related function. The USB-related circuit design is shown below: NC Pin Explanation: Originally designated as IO16/D11 pin, it is now changed to NC pin, which means it should not be used for any other functions. Please refer to the datasheet for the reasons behind this change.
