To directly program LimeSDR-Mini FPGA Intel MAX 10 (10M16SAU169C8G 169-UBGA), it is needed to connected JTAG adapter (Altera Blaster or equivalent). Standard FPGA JTAG connector has 10 pins in 2x5 configuration with 0.1" (2.54mm) pitch. Standard JTAG connector is too large for such a small PCB as LimeSDR-Mini. For this reason, Limemini has 2 non-standard JTAG programming connectors:

* 7 pin (0.1") male header on the board edge
* 10 pin (0.05") female header

== 7 pin JTAG connector on the board edge ==

To use this JTAG connector with standard JTAG adapter you need to make simple JTAG adapter. LED is optional component and is required only for power indication.

== 10 pin JTAG connector ==

This connector has standard FPGA JTAG pinout pinout, but smaller pitch (0.05").
