3D printed Stepper Bot
ElectroPoint4u Dec 03,2021
This is a E.S.P32 based robot that I made which can not only be controlled over the internet but also can sense its surroundings for any obstacle that might get into it’s path.I have used Nema 17 stepper motors for precision controlling and DRV8825 Stepper drivers to drive the motors.The case and wheels are designed in fusion 360 and entirely made out of 3d printed parts.And I have designed a custom PCB to connect all the electronics.The bot has VL53L0X Time-of-Flight ranging sensor in four corn...

ESP32 LED Controller Board
Mark Wu Nov 30,2021
The PCB gerber submitted is a new design for the prototyped circuit we have made for a hackathon. Here is its description.## InspirationAs more and more people have been working from home, the problem of natural lighting has been growing. During the pandemic, we personally experienced this issue because we lived in rooms where sunlight was scarce. The constant intensity and hue ceiling light made motivation very dull.## What it doesWith our custom code, the kit fetches the time from an NTP serve...

buttonBoard_V1.2 - A multipurpose ESP32 powered IOT button PCB
Nerdiy.de Nov 22,2021
The ButtonBoard PCB is my attempt to kill several birds with one stone. On the one hand, I’ve always been looking for a universal and easy-to-program remote control for the often very individual control options in my smart home. On the other hand, I wanted to have a simple way of equipping my projects (for example the pxlBlck project) with a physical operating option. Currently, the various pxlBlck platforms can only be controlled via the serial interface or an existing WiFi conne...

DIY - NodeMCU Development Board
Adhikari Nov 21,2021
If you have ever programmed a NodeMCU, then I bet you know the pain you have to go through while connecting sensors to NodeMCU on a breadboard.I looked for various solution on the web and found "NodeMCU Development Boards" for around $6 to $7. Well, I wasn't ready to spend that much for a simple projects. So, I went ahead and designed a replica of those boards, which, 10 of them I got fabricated from PCBWay for just $5.PCB DesignLet me first show you the design of the board.I have placed the Nod...

Mini T3.2 - Miniaturization of Teensy 3.2 board
FRDM4236 Nov 15,2021
Teensy 3.2 is a great microcontroller board and it's one of the most popular development boards in the Arduino world. Inspired by a user's project on the PJRC forum, https://forum.pjrc.com/threads/33347-Tiniest-Teensy, I have made the Teensy 3.2 board smaller. The Mini T3.2 board is a small Teensy 3.2 compatible board and is based on the same MK20DX256VLH7 microcontroller as the Teensy 3.2 is. It will work with Teensyduino as a regular Teensy 3.2.Note: The Mini T3.2 board includes a built-i...

Soil Moisture Sensor ESP32 PCB
_adikar Nov 08,2021
Project BackgroundI am very fascinated by technology since my childhood. I like working with electronic gadgets and I am very keen in developing things on my own. Hence, I decided to design a circuit based on the ESP32 IoT development module.Circuit DesignThis circuit consists of a ESP32 development board, a soil moisture sensor and an OLED display. The ESP32 module powers up both the Sensor and the display.The soil moisture sensor has 2 probes attached to it. These probes go into the soil. Thes...

uTerm2-S: a multi-emulation color RS232 terminal
Just4Fun Oct 18,2021
* * HARDWARE OVERVIEW * *The uTerm2-S (micro Term2 stand-alone) is an easy to build multi-emulation RS232 terminal using an ESP32-Wroom-32 module and the great FabGL library (http://www.fabglib.org). More, using an ESP32 gives the opportunity to use the uTerm2-S in a lot of different ways easily using the Arduino IDE with the ESP32 core.These the main specs of uTerm2-S:RS232 serial port;VGA output;"transparent" port for a serial-USB adapter (as in the uTerm-S);secondary serial port for ESP32 pro...
