This document introduces the TOPPIC single-chip microcontroller experimental development system, a high-quality product from AJDZ.net that is affordable for everyone. The system is characterized by modularity, openness, and multiple functions, and is suitable for basic verification experiments and development of PIC single-chip microcontrollers. The system features a PS/2 keyboard port, USB data interface, SD card module, 8x8 LED dot matrix + 8-channel LED composite module, three-input safe power module, RS232 serial port, 4x3 matrix keyboard + 4-channel independent button composite module, multi-function analog A/D and comparator input port, and multi-function motor and relay drive port.
The TOPPIC development board is a versatile microcontroller platform that integrates common interfaces such as USB, SD‑card, 8×8 LED matrix, 1602 LCD, DS1302 RTC and DS18B20 temperature sensor. It is designed for students and hobbyists to experiment with PIC, AVR and 8051 based microcontrollers and to quickly prototype embedded applications.
The manual describes the board dimensions, power supply options, pin‑out diagrams, and step‑by‑step programming using MPLAB IDE with an ICD2 programmer. It also explains how to connect external peripherals via the provided connectors and how to use short‑circuit jumpers for flexible hardware configuration. This manual is written in Japanese.
