![]() ![]() You can also order Housings ( from 1-20 and multirow) where you can insert the crimped wires and make a "One Touch" Connector for a couple of wires to the arduino. ![]() But Soldering and "thermic shrinkable tubing" is lots of work. ![]() Stephans System is pretty cool and will work perfect. Premium Black Solder Mask Identical DIP8 Form Factor Pre-soldered for Easier Soldering. ( Just google for Precission non precission to see difference) EDIT: Picture show female. connector, brush ch341a, eeprom adapter upa usb programmer, ch341a. These are bigger and nearly same like "non precission pins". I order in the past some "Crimp Dupont contacts" like this. So this pins are not good for a permanent connection ( simply cause they are to smal and can fall out of the MEGA) ![]() Means the diameter of the Pin needles are smaller like the "Non precission" Pins. The Dupont Wires (Jumper wires like this ) you get with your mega ( for example in Laboratory set with Breadboard ) are "mostly" "precission". This eliminates the need to unnecessarily spend money on the shields you mentioned. But even here you can help yourself by creating a central GND point on a small piece of breadboard. For non-ratcheting pliers, it’s suggested the connector be re-crimped with the next smallest. The situation is different with the GND supply. Then, put the connector into a suitably sized space in the jaws, insert the wire, and crimp it down. Before the solder steles on the pin headers pull shrink tubing with adhesive over the cable ends and finished are perfect connections.Īs far as the power supply to the power supply via the MEGA is concerned, I basically agree with you. These can be cut to the required requirements, are in the 2.5 mm grid (0.1 inch grid) and ensure a secure contact. Screw or clamp connections have the disadvantage that they stress the cables mechanically.Īt the transitions, for example cable -> MEGA, the cables should be soldered to the connector. They are not suitable for the final construction.īasically, cable connections should be soldered. Last edit at 10:41AM by qrp-gaijin.The DuPont cables are designed and intended solely for experimenting with the breadboards. What do you RepRappers think? Is 28 AWG ribbon cable safe to use for connecting to 1.2A stepper motors?Įdited 1 time(s). That reference says that "max current for chassis wiring" for 28 AWG ribbon cable is 1.4A. My plan was to cut these wires in half (leaving a 5-cm length of four 28 AWG wires, connected to the 4-pin DuPont connector) and solder the individual wires to the existing long wires on my stepper motors.Īssuming the original and existing wire gauge on the stepper motors is adequate for the required currents, then my question is: is it safe to use an additional 5-cm length of 28 AWG thin wire to connect the existing thick wires to the control board? This implies there will be a short 5-cm run of thin wires with possibly insufficient current-carrying capacity, but since the thin wires are so short, maybe it would still be safe since the heat buildup over such a short length of wire wouldn't cause problems.įurthermore, it seems that 28 AWG ribbon cable might in fact be able to handle the 1.2A current from the stepper motor. My stepper motors are marked with "1.2A" on the housing. Make a Good Dupont Pin-Crimp EVERY TIME: Anyone working with an Arduino, Raspberry PI, Beagle Bone, or any other multi-circuit-board project has become familiar with. I failed to consider the required wire gauge, and after receiving the cables and doing more research on similar cables, I think that the cables I bought have 28 AWG wire. ![]()
