connectorless-zigzag-1x6-mini-isp-connector

An Arduino ISP connector is used, among others, for burning a bootloader and for programming ATtiny chips. When the ISP connector is only used once, it would be more convenient not to use a connector. Therefore, I created the connectorless 1x6 mini ISP connector and the mini 1x6 ISP adapter. By the zigzag positions of the PCB holes, the male ISP connector pins press against the holes and make electrical contact and so, no PCB connector is needed.

fdti-updi-connector

Typically, debugging via the serial monitor and burning the bootloader requires 2 connectors: FTDI For debugging and uploading the sketch UPDI For burning the boot loader (like the ICSP connector for the Atmega328 and others) These connectors, however, take up a lot of space on the pcb, especially with respect to the fact that the ATtiny devices, such as the ATtiny3217, are very small. That is why I have designed a new combined FTDI / UPDI connector, which take less space on the pcb.
