After uploading the code, your USB Mini Programmer will be ready for use.
Now we need to make a circuit for this project with all the components, place it on your breadboard then upload the code using Arduino IDE. I hope that you have done everything properly in terms of hardware supply and software installation in steps 0 and step 1. 4 x Push Button (One for Enable/Disable Reset and one for Exit/Program Mode)Ĥ) USB Cable (A Standard A to B cable will be fine).2 x 220Ω Resistor (One for each color LED).You will get this type of programmer in some cheap Chinese modules that you buy online actually, however, if you are interested in doing it yourself, then follow these step-by-step instructions.Ģ) Breadboard (I prefer having min 2 * 4 holes breadboard for better stability) This tutorial is for making your own USB Mini Programmer using the CH341A chipset.

Check out this article about how to make an in-circuit USB Debug Tool/Programmer with a 328p AVR microcontroller using FT232RL. So having an inbuilt connection in your prototyping board can save both time and money. You can refer to the datasheet of the CH340/CH341 page for more details about this product.Īs I mentioned earlier in my previous article about FT232RL, when you are working with these devices, connecting wires back and forth to your breadboard takes lots of time when you are doing some experiments or prototyping your circuit.
It works with microcontrollers that have an RS232 port, also it supports two different voltage levels (5v or 3.3v) for communication.
