The Mcu8266 via the SPI bus controls the six 1000ohm digital potentiometers offered by the AD8403 and AD8402 chips. the six potentiometers are placed in parallel and in series with a resistor and timm...
Card for the generation of signals produced by DDS AD9833 enslaved to MCU Esp8266. The signals can be varied in frequency (1: 300) KHz, in Amplitude (0:24) Vpp and in Offset (-8: +8) Volt. The command...
Card is made up of mcu-ESP8266 and PCF8575 module for reading 16 digital inputs. The value of the bits are displayed locally on the OLED display and sent when requested via WiFI to the remote server ...
Generation of a sinusoidal and cosinusoidal signal of 100 Hz ,with variable offset and amplitude controlled via WIFI and manually. It uses Heltec esp8266 Wifi kit8 MCU for communications and signal g...
The board was built to generate two voltages (mV) isolated from each other and from the ground by emulating that produced by a thermocouple already compnsata by a cold junction of zero degrees. Some p...
The board consists of the mcu-ESP8266 module and 4 modules with ADS1015 for the A / D conversion of the 16 inputs. The chip shown converts the analog size to 11 bits + sign. By inserting in parallel...
Board is made up of mcu-ESP8266 and PCF8575 module for writing 16 digital digital outputs. The value of the bits are displayed locally on the OLED display. The commands are sent via WiFI from the rem...
