This ESP32 4.3 inch IPS display could be an ideal displayer& controller for IoT applications.

I have made a lot of ESP32-related boards, but there actually some problems we encountered, the most problem is its ADC. Check my test result and some cautions in Using ESP32 ADC.

I made a LoRaWAN soil moisture sensor, based on RP2040. But there is still some difficulty with the low power consumption...

Using ESP32-S3 TFT touch as UBS HID devices, the ESP32-S3 native USB is used, which can be used as a USB HID to simulate a custom keyboard.

After the long pause of production due to the IC shortage, finally, Hermes Lite 2 is back to re-production, and the group buy is already opened.

Makerfabs Lora Soil Moisture Sensor v3, now supported the Lorawan!!!

For these customers that need a longer distance, the ESP32 UWB & UWB DW3000 40m+ distance seems not enough, as suggestion and after our testing, we make this high power version, with this version, the max distance can be up to 120m, that more suitable for applications such as outdoor positioning/ large storage positioning.

CFexpress Type B Card Reader, the world's 1st true LEGO-compatible case solution.

Dual Edge TPU Adapter is designed for Coral m.2 Accelerator with Dual Edge TPU to be used on a system with PCIe x1 slot available.

ESP32 UWB DW3000, which is Interoperable with Apple U1 chip, makes it possible to work with the Apple system.

Makerfabs MaPIE Lora is based on Raspberry Pi PICO RP2040 controller, with integration of flash and Lora RFM98W, to make it a good platform for RP2040 development of Lora applications.

In this video, we made a comparative test between the normal version ESP32 UWB and the High power version with amplifier ESP32 UWB.

The result: Normal version distance: appx 42m; High Power version distance: appx 120m.

So the ESP32 UWB high power version with amplifier, max distance up to 120m~

This Lora - 4 Channel MOSFET Driver makes it easy to control FANS/DC motors/ Solenoid/ Electromagnetic Lock, etc... with Lora.

Use your Raspberry Pi with LTE Cat-4 4G / 3G / 2G Communication & GNSS Positioning, for remote data transmission/ phone/ SMS, suitable for remote area monitoring/alarming…

In this article, we will talk about the ESP32 UWB Antenna delay calibrating, let's see how to calibrate and the UWB antenna calibrating result.

ESP series are very popular in makers' projects, ESP8266 and ESP32 are the most commonly used, We will talk about those 2 ESP series from Espressif, and some ESP8266 and ESP32 related products designed by Makerfabs.

Makerfabs Lora TDS sensor monitors the water status, includes TDS/ temperature, and sends the data remotely via Lora, to create a local Lora network.

In the past few months, we made a big upgrade for the new version of Lora soil moisture. In this article, we will introduce the great improvements on Makerfabs Lora Soil Moisture sensor V3!

New product

The Maduino Power-Line Communication(PLC) module has an onboard Atmega328p MCU for custom firmware development in the popular Arduino and Atmel Studio development environments; enabling one to create a custom smart home device and or powerline smart home network.

Makerfabs Lora AC Dimmer chopper circuit is based on Triac BT139, and zero-cross checking circuit, it detects the zero-cross points and then the Triac controlled to chop the AC.

As the serious worldwide IC shortage recently, there're so many ICs out of stock, many of our customers have to modify the designs to BGA components. So, for makers: BGA? or Not?

Step by step guide

You will see 9 steps in this video: Step 1: Components re-Shaping Step 2: Place the Components Manually Step 3: Visual Checking Step 4: Fix the PCBA onto Jig Step 5: Wave Soldering Step 6: Other Processing ---6.1 Cut the Pins ---6.2 Manually Soldering ---6.3 Mount Screws Step 7: PCBA Cleaning and Polishing Step 8: Final PCBA Checking and Repairing Step 9: Final Visual Checking

I met a problem in ESP32, that I have to reprogram the ESP32 every time I changed a location, here I found a solution and this is a tutorial shows how to connect ESP32 to wifi without programing.

This is an Arduino tutorial for starters: Getting Started with Arduino, learn how to control a LED light, we will make a DIY LED clock.

Once I failed to control the drone because of the wind, I want to measure the wind speed to know whether it is suitable for the drone flight in the wild. How to measure the wind speed in the field and be viewed anywhere? It requires the MQTT communication to get the speed of wind.

In this project, I want to simply introduce the MQTT and show how to build an MQTT network to get the wind speed of a specific place.

In this video, we will take a factory tour to know the FPC assembly process.

FPC(Flexible Printed Circuit) refers to a thin insulating polymer film having conductive circuit patterns affixed. The most advantage for FPC is flexibility, which allows it to be a good connection within a compact space or parts that need to bent.

In this tutorial, we will learn how to use Arduino code to implement CANBUS communication with DHT11 sensor. We will also using an OLED in this project, so we can display the temperature and humidity on it.
