Abstract

This paper presents the development of an open-source, low-sized, BGA microcontroller breakout board, that can be used for the development of wearable and cyber-physical prototypes. The board is based on the low power, 8-bit, ATtiny20-CCU Microchip AVR microcontroller. The ATtiny20-CCU can be programmed without bootloader, using the Atmel Tiny Programming Interface (TPI), instead of In-System Programming (ISP). The C code used to program the microcontroller can be written and compiled using the Microchip Studio freeware platform. The ATtiny20-CCU Ultra Fine-pitch Ball Grid Array (UFBGA) packaging technology allows the shrinkage of the conceived Electroless Nickel-Immersion Gold (ENIG) Printed Circuit Board (PCB) to a size of only 155 × 13 mm. Its low cost also makes it a viable option for developing many educational electronic projects, especially for Instrumentation and Assistive Technology. The contribution of this paper is mainly the hardware prototype design, the PCB manufacturing, building and test of a very low-sized open source -breakout PCB board, for wearable Instrumentation applications, towards the emergent Society/Industry 5.0.

摘要

本文介绍了一种开源、小尺寸的BGA微控制器开发板，可用于可穿戴和信息物理原型的开发。该开发板基于低功耗8位Microchip AVR微控制器ATtiny20-CCU。ATtiny20-CCU无需引导加载程序，而是使用Atmel Tiny编程接口（TPI）而非在线系统编程（ISP）进行编程。用于对微控制器进行编程的C代码可以使用Microchip Studio免费软件平台编写和编译。ATtiny20-CCU超精细间距球栅阵列（UFBGA）封装技术可将设想的化学镀镍浸金（ENIG）印刷电路板（PCB）缩小到仅155×13毫米的尺寸。其低成本也使其成为开发许多教育电子项目的可行选择，尤其是用于仪器仪表和辅助技术。本文的贡献主要在于针对新兴的社会/工业5.0，为可穿戴仪器应用设计硬件原型、制造PCB、构建并测试一个尺寸非常小的开源开发型PCB板。
