采购商询盘内容

I'm reaching out to get some clarification on the pin connections for the Arduino UNO. I've been able to send data to the shield using RX1 and TX1, but I'm having trouble receiving data from the buttons. I've tried numerous configurations (over 20 options) without success, and I really need some guidance since my deadline is approaching quickly. Additionally, I'm looking to purchase 140 units of these shields. I've already soldered the jumper, but any suggestions you can provide to help resolve this issue would be greatly appreciated. Thank you!
我联系您是想请教一下关于 Arduino UNO 引脚连接的问题。我已经能够使用 RX1 和 TX1 向扩展板发送数据，但是无法接收按钮发送的数据。我已经尝试了多种配置（超过 20 种），但都失败了。由于截止日期临近，我急需一些指导。 另外，我打算采购140个这种扩展板。我已经焊接好了跳线，但如果您能提供任何建议来帮助解决这个问题，我将不胜感激。谢谢！
