I propose a guaranteed quality, I currently have experience with NXP, Arduino and ESP32 microcontrollers. I also have advanced experience with touch screens, servomotors, CD motors, sensors, etc. I have a wide range of components to work from now on. I will include a technical report with all the specifications you need and with the firmware in a transparent way. I have experience in bluetooth applications using the HC-05 module that communicates with the microcontroller by serial port and I have experience in low power bluetooth. I have experience using EAGLE CAD 8.3.2 in multilayer designs.I have experience with Nodemcu and Cayenne! Can you see my hackster profile about my recent electronic maker. [login to view URL]
