This guide covers the operation, connection methods, and programming procedures for the QL120_A3 universal programmer adapter designed for 5V PIC devices.
The QL120_A3 is a next-generation universal programmer adapter developed by Shenzhen Qianlongsheng Electronic Technology Co., Ltd. It supports programming all 5V-powered PIC devices with up to 40 pins by connecting to programmers such as ICD2, MCD2, or PICKIT2 via an ICSP interface. This manual is written in Chinese.
| Supported Devices | 5V-powered PIC devices with 40 pins or fewer |
|---|---|
| Compatible Programmers | ICD2, MCD2, PICKIT2 and others with ICSP interface |
| Power Supply | 5V external power required for MCD2/ICD2 |
You can use the 9 built-in surface mount positions on the right side to press-fit and burn chips directly without connecting jumper wires, though this is not suitable for batch burning.
LED1 indicates that the user board power is active; it only lights up after ICD2/MCD2 establishes normal communication with the computer and supplies 5V voltage.
