This is a battery powered sensor board based on the ESP8266 (ESP-12F).
By using a TPL5111 chip the battery consumption can be reduced to about 1µA when the ESP is not enabled. When the TPL5111 chip receives 5V at it's wake up pin this will turn the ESP on by enabling the 3.3V voltage regulator. At this moment you can run any program you want. If you want to turn the ESP off again you have to drive...

EN - This is a digital servo tester using a simple Attiny44 chip.
Code can be downloaded from http://bit.ly/2wBhLwt
(Also need software servo library found here https://playground.arduino.cc/ComponentLib/Servo/ and to program from Arduino need these boards https://github.com/SpenceKonde/ATTinyCore/blob/master/Installation.md)

EN - Used to program custom functions in it and be able to perform NAV lights, dual servo sequences, sensor triggered actions and similar simple tasks. It should be programmed with the Arduino IDE after installing the ATTiny Core in the board's manager - https://github.com/SpenceKonde/ATTinyCore ...For easy programming use the Uno shield found here https://easyeda.com/Joyvel/programing-for-attiny-...
One of the key concepts in electronics is the printed circuit board or PCB. It's so fundamental that people often forget to explain what a PCB is.
#What is a Printed Circuit Board?#
A [printed circuit board (PCB)] is a plastic board made for connecting electronic components together. These are used in almost all computers and electronics today.
A printed circuit board (PCB) mechanicall...
I tried a new **quick turn PCB fabrication**:[JLCPCB ](https://jlcpcb.com/m ), Here is the review about JLCPCB. Since I still have some older versions of one of the boards, I could make a comparison with the two **quick turn PCB fabrication**. I decide to not mention which competitor I pitched JLCPCB against...
**Stun gun** is a device which generates high voltage at it’s output by taking low voltage as input. Concept of this device is based on High volt inverter. Here we are building this **Stun Gun circuit on PCB** and below you can find the required circuit diagram and PCB layouts to build this stun gun yourself.
For complete details about the circuit with instructions on how to design this circuit...
Carte d'asservissement d'un robot pour la coupe de france de robotique.
La carte comporte deux régulateurs de tension, un variable et un 5V.
La position du robot est calculée en temps réel par la carte STM32L432KC à l'aide des encodeurs. Suivant la commande reçue en I2C, un signal PWN est envoyé au L298N pour contrôler la tension des deux moteurs.
[Multilayer PCB](https://www.theengineeringprojects.com/2018/03/multilayer-pcb.html) is an integral part of most of the electronics when it comes to connecting number of electronic components on the board. [Multilayer PCB](https://jlcpcb.com) helps us getting rid of the old ways of joining components where components were joined together by end to end wiring, resulted in covering more space and we...
An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow. To be referred to as electronic, rather than electrical, generally at least one active component must be present. The combination of components and wires allows various simple and co...
