Which programmer to choose for arduino?

Question

Arduino

Hello, I want to buy a programmer for boards such as arduino mini, pro, pro mini.
Is it possible to use one programmer for all these boards?
I looked at Ali, will this one suit me ?
Thank you very much in advance!

Answer 1

An Arduino with a built-in bootloader can be flashed via UART, while a clean controller is flashed via SPI. The TTL you suggested is suitable for flashing an arduin without a built-in converter (pro. mini, micro, etc.), but it does not have a DTR output, you will have to press reset on the arduino with each flashing. There are the same converters, but with the DTR pin output, then it is not necessary to reset the arduin, it will be flashed in the same way as uno / nano using native usb.

in fact, it’s not even a programmer, but a USB-RS232 converter, more precisely USB-UART, because for RS232 you still need to form the appropriate levels, which this converter does not do (at least my PL2303 is so accurate)
on the issue of programming - in fact, you there is an arduino, because it can be used as a programmer.
well, if you want a separate programmer, then you need to look towards AVR ISP, USBasp, but here you already need to understand that you will work directly with the ATMEL AVR controller, you need to know about fuses and so on.

Answer 3

Why Arduino programmer? Plug and paste sketches into USB...

Answer 4

Buy a regular UART converter on a prolific chip

Answer 5

This is not a programmer. This is a virtual COM port for USB. If you need a programmer, then USBASP will do.
