This document introduces the features and usage instructions of the 61 board development board for Lingyang University's plan. It includes hardware diagrams, usage steps, and interface specifications. The development board is based on the SPCE061A microcontroller, with DSP and voice processing capabilities, and is suitable for university students, electronics enthusiasts, and microcontroller learners.
The 61 Board is a compact development platform built around the SPCE061A 16‑bit microcontroller, aimed at university students and electronics hobbyists for hands‑on learning and project development. It includes a minimal system circuit, power and audio circuits, reset circuitry, and supports DSP and voice processing functions.
The manual covers the board’s hardware block diagram, power options, I/O and audio interfaces, programming methods using EZ‑PROBE or PROBE, and a series of experiments ranging from LED displays to UART communication and voice playback. Component lists, schematics, and contact information are also provided. This manual is written in Chinese.
| Core voltage | 3.3 V |
|---|---|
| I/O voltage selectable | 3.3 V or 5 V |
| Power supply options | 3× AA batteries, 5 V DC, or 3.3 V DC |
| Number of I/O pins | 32 |
It can be powered by three AA batteries, a 5 V DC source, or a 3.3 V DC source, with voltage regulation provided by the SPY0029 regulator.
Set switch S5 to the PROBE position (near J4) for probe use, or to the EZ‑PROBE position (near J11) for EZ‑PROBE; after downloading, move S5 back to the PROBE position for offline operation.
The board is based on the SPCE061A 16‑bit microcontroller.
The board provides 32 I/O pins across PORTA and PORTB.
