I’ve made a small 3-axis CNC machine for engraving with a small spindle and 300mW laser diode. I want to engrave raster images and added a Laser Diode Driver with TTL modulation. I am not sure how to connect the TTL, -ve goes to ground but which pin on either the Arduino CNC shield or Arduino UNO will provide the modulation for TTL +ve?

Mar 23, 2018 · Going to the Digi-Key website and searching for an “Arduino Ethernet shield” returns a couple of results. While the Arduino V5.0 Ethernet Shield is not listed, a more modern version is (based on the W5500), and a datasheet is also available for the shield (this is very important). Arduino Ethernet Shield Overview The Arduino Ethernet is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins, 6 analog inputs, a 16 MHz crystal oscillator, a RJ45 connection, a power jack, an ICSP header, and a reset button. This data logger shield provides an Arduino Uno, Leonardo, or Mega with the ability to log sensor data to an SD card with the minimum of set-up. The shield provides several useful features: Real Time Clock Module The shield includes the very popular DS1307 battery backed real time clock (RTC).
