ESP ProgrammerA USB programmer for the ESP8266 or ESP32 chips from Espressif Systems. This board uses the CH340 USB to serial interface to program the ESP devices. The board also uses the GPIO0 and Reset lines to aid programming, just as Wemos and NodeMCU development modules. Using an external programmer makes the target board easier and cheaper to build without the USB interface, this also aids with lower power modes used for battery operation. Not having to power the USB interface can save precious battery power.
USB Programmer for Sonoff RelaysA USB programmer is for the ESP8266 used on the Sonoff Relay modules.
To set the ESP8266 into programming mode.
Press and hold the push button on the Relay board (GPIO0).
Press and release the power button on the programmer.
Program the device and keep the relays push button pressed until done.
ESP8266 Mains Power SensorSingle phase mains power sensor using a current transformer (not included) and a Wemos D1 Mini (not included). The transformer used is a "Current Transformer AC current sensor 100A SCT-013-000" available on eBay. This plugs into the sensor PCB and the ESP8266 (Wemos D1) and uses the analog input to measure the mains current draw. The Wemos is powered by it's micro USB input. This makes a very simple sensor setup that could report the measured current via MQTT. A simple case design is also available on Thingiverse.
ESP8266 4 Channel Mains Power Sensor
4 Channel mains power sensor using a current transformer (not included) and a Wemos D1 Mini (not included). The transformers used are "Current Transformer AC current sensor 100A SCT-013-000" available on eBay. This plugs into the sensor PCB and the ESP8266 (Wemos D1) and uses 4 channel A/D (ADS1115) to measure the mains current draw.
Wemos I2C Sensor Board
For use with any I2C sensor such as the popular UV VEML6070.
The board has on-board 5V regulator so can be power by an external 12V supply.
Also mounted on the board is a speaker with transistor driver.
A USB powered relay for controlling anything USB powered via WiFi.
Uses a ESP-12 module to control a relay, only the power is controlled the data lines are permanently connected.
Also included are a couple of LED indicators and a push button for local control.
ESP8266 PIR Sensor
A WiFi enabled PIR motion sensor using the ESP8266.
The sensor used is the AM612 and the WiFi module is the ESP-12.
ESP-01 Temperature and Humidity SensorThis simple board connects an ESP-01 Wi-Fi module to a AM2301 Sensor. Ideal for a simple indoor wireless sensor for temperature monitoring or control.
Wemos - WS2811/WS2812 LED Driver BoardThis board connects the popular Wemos D1 Mini to the very popular WS2811/2812 LED strips.
The board has a 3.3V to 5V line driver for the data and 5V regulator for use with 12V LED strips
ESP-01 - WS2811/WS2812 LED Driver BoardThis board connects the popular ESP-01 to the very popular WS2811/2812 LED strips.
The board has a 3.3V to 5V line driver for the data and 3.3V regulator for the ESP-01
80mm Matrix Prototype PCB - With ESP8266
A prototyping breadboard with a 5V input and a 3.3V regulated power supply plus a reset push button.
A speaker with driver circuit for playing alert tones. Also a prototyping area with over 300 holes on a 0.1" pitch. Two bus rails are provided for power, one ground and one +3.3V.
Solder pads provided for ESP12 modules (not incluced) and connections for an external programmer.
