Shield for Wemos D1 Mini. It provides two 3.3V GPIO and two 5V GPIO each with supply voltage, and ground terminals.
The two 3.3V GPIO have provisions for optional pullup resistors. These can be used with sensors or 1-wire devices requiring pullup.
Two additional GPIO are for 5V devices with level shifters to provide 5V Input or Output that is compatible with 3.3V GPIO on the Wemos.
This shield is designed for easy powering and using four 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.
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.
# 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.
Template (PCB and interface symbol) to copy for any kind of shield designs for Raspberry Pi B+. The PCB contains 6 layers with layer display at the lower edge. The assignment of layers is:
- top: signal, polygon connected to GND
- bottom: signal, polygon connected to GND
- layer 1: inner, signal
- layer 2: inner, polygon VCC
- layer 3: inner, polygon GND
- layer 4: inner, signal
To test the series of sensors contained in the package "37 in 1 Sensor Module Board Set" which is sold by many sites it is possible to use this shield compatible with Arduino UNO original R3 and related clones.
On the board are available many connectors that are already properly connected with the digital or analog ports of Arduino.
In fact, the card, in addition to the sensors in the "37 in 1 Sen...
A simple ethernet shield for Wemos D1 Mini based on W5500 respecting WizNet directives (https://wizwiki.net/wiki/doku.php/products:w5500:start).
All SMD components are chosen such that JLCPCB can mount them. The only exception is the crystal; replace it with X322525MOB4SI (adapting both schematic and layout) if you want it mounted.
Since JLCPCB can mount either top or bottom only, all the SMD co...
