so, I'm working on a project and decided it would be nice to have a small pcb for me to work on the communication between two atmega microcontrollers.
I designed as a very small development board with a UART connector to debug the RF24 communication but also so the whole board can be used as a shield, after.
My intentions are that, after I manage the RF stuff, I can use the board to input data...
# ESP 32 input output board/ shield #
8 opto-isolated inputs
8 10 amp relay outputs
Serial, 1 Wire comunication ports.
Just plug in a ESP32test module and programm it.
Used it with Jeedom and the Jeeduino plugin.
This is not in any way my design or idea. It's based on the work of Daniel Perez over at https://generatorlabs.wixsite.com/spectrum.
I just converted the pdfs of the schematics and made some small improvements for easier connectivity, to allow anyone who want to build it theirself.
I thank him so much for sharing this awesome project along with the arduino code. Please check out his 3 part video...
# Shield fo Raspberry PI zero W. #
# Introduction #
This shield created for moving many digital servos as [LOBOT LX-16A or LOBOT LX15D](www.lobot-robot.com).
# Desing #
This shield included microcontroller stm32f413 and st-link scheme on stm32f103 base. Stm32f413 connected to raspberry connector via SPI, UART and I2C interfaces. You can to use stm32f413 as:
- USB/UART bridge for raspberry cons...
A custom shield for using a SIM800L-based GPRS transceiver to connect to the internet over GSM. This is designed to be driven by a SparkFun SAMD21 Mini board, and includes a 128x64 OLED display and an NRF24L01+ 2.4GHz RF module. It's powered by a lithium-ion battery (18650), and has a microSD port to archive data.
This shield is designed for easy powering and using two GPIOs of ESP-01/01S module. It is powered by 5 volts DC and has four 3-pin screw terminals for connecting some periphery like 2812 LEDs, relay modules, etc. Also it has a 3.3v power supply on board
# Multi purpous PWM led driver #
WiFi PWM Led driver light hub for white, warm white, rgb etc use (8 chanels).
Connects to home automation system (for exemple Jeedom).
This drives series/parallel led strips, not adressable leds / led strips.
2 PCB designs to be able to mount it in round or rectangular enclosures.
A collection of protoboard designs, all ready-to-order via your favourite PCB manufacturer.
Boards in the collection:
- Breadboard-compatible - all with power rails on both sides as well as extra holes and pads for connecting power:
- Small (15 rows of 2x5 points)
- Medium (30 rows of 2x5 points)
- Large (60 rows of 2x5 points) in two variants: a) with continuous power rails, b) with...
