The ESK-302 is a start kit designed for the HT66F70A.

ESK-302 mainly has two functions : OCDS function and ICP function. The OCDS (On-Chip-Debug-Support) function is useful for program development and debugging, it works with the HT-IDE3000 software. The ICP (In-Circuit-Programming) function is used to program to the HT66V70 MCU on the board. It works with the HOPE3000 for e-Link software.

1. When using ESK-302 for OCDS debugging, only the e-Link Lite USB port is required for power supply. The HT66V70A can not be connected to an external power supply, otherwise there will be voltage conflicts.
2. Only the e-Link Lite USB supplys power. There will be no voltage output for the HT66V70A. There will be voltage output only when the HT-IDE3000 is running at full speed.
3. If the HT66V70A is connected to an external power supply, be sure to disconnect the e-Link Lite to prevent the voltage from being reversed to the e-Link Lite and causing interference to the HT66V70A.
