Elecrow is a professional expert who can meet the requirements of PCB assembly, PCB manufacturing, PCB layout, PCB prototyping and PCB rework. Elecrow has a mature system and various testing methods to ensure manufacturing your PCBA with high quality. 

The Raspberry Pi is a very cheap computer that runs Linux, but it also provides a set of GPIO (general purpose input/output) pins, allowing you to control electronic components for physical computing and explore the Internet of Things. Crowpi-L is a real Raspberry Pi computer for learning programming and hardware. Crowpi-L is a real Raspberry pi laptop for learning programming and hardware.

Elecrow collected several common process defects in PCBA processing to help you to avoid detours. Learn these PCBA process defects and get twice the result with half the effort in the design phase.

Big price drop!In response to customer demand and maximize cost savings for customers,We have recently reduced the cost of PCB stencil by improving our work efficiency.The lowest price of SMT stencil decreased from $9.8 to $5!

Elecrow Arduino Automatic Smart Plant Watering Kit can water 4 pots of plants at once by detecting the soil moisture value, helping you become a green thumb.

The hottest module on the Internet of Things in the past few years is ESP8266, but now the hottest module is ESP32! It is easy to confuse that ESP32 is actually a control chip on the development board, not a development board! The Most Popular WiFi & Bluetooth Module in 2021 is ESP32-WROOM-32D.

ESP8266 is a low-cost and high-performance wireless SOC, which provides endless possibilities for integrating WiFi functions into other systems. It can control input and output like Arduino, but the special feature is that it comes with Wi-Fi. ESP series Wi-Fi modules are popular in IoT projects.

However, due to the fast update iteration speed and lack of module-related information, there are some confusions between ESP-12E Wifi Module and ESP-12F Wifi Module.

We reviewed the original CrowPi back in 2018 and considered it to be a well-built device that would be an excellent way for someone to get into STEM.

For those who do not know, CrowPi2 is a device that is aimed at helping people get into computing. The idea is to provide an all-in-one package where people can easily interact with a variety of sensors.

In the last blog post we have introduced the features of the Crowbits, which is a set of color-coded and magnetic electronic modules that teaches students about programming, electronics, design thinking, and logics. Today, we are so happy to announce that Crowbits STEM Education Kits is coming soon.

If you work on a Raspberry Pi project or building a deskstop with Raspberry Pi, a choice of Raspberry Pi display is significant. Here is the overview of displays you can choose in your project
