ESP32 Sensor Network


The ESP32 Sensor Network is a WiFi/BLE/Bluetooth based wireless sensor network that can connect with a variety of sensors.

This module is a comprehensive development platform for Espressif's ESP32. Like the 8266 and ESP32 Thing, the ESP32 Sensor Network is a WiFi-compatible microcontroller with support for both Bluetooth Classic (i.e. SPP) and Bluetooth low-energy (i.e. BLE, BT4.0, Bluetooth Smart), a Qwiic connector, and 21 I/O pins. Add to that a rich set of peripherals ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPIs, UARTs, I2S and I2C.


You can download the files from GitHub and feel free to replicate them for your projects!


Note that this board doesn't come with a USB to serial converter chip and auto-reset circuit. Instead, you will need to plug in a CP2104 Friend or FTDI cable. Then, before uploading code, put it into bootloader mode by holding down the Boot button and clicking the Reset button, then releasing the Boot button.


Features:

  • Xtensa® dual-core 32-bit LX6 microprocessor

  • Up to 240MHz clock frequency

  • 16MB of flash storage

  • 520kB internal SRAM

  • Integrated 802.11 BGN WiFi transceiver

  • Integrated dual-mode Bluetooth (classic and BLE)


This module uses is compatible with ESP32 WROOM 32E or ESP32 WROOM 32DA.



Note: This is a 2 layer board (35mm x 48mm) using ESP32 WROOM modules. There's another board designed for Micro Sensor Networks which is a 4 layer board using ESP32S.


Feel free to contact me if you have any queries.



Happy Making!
