HomeAssistant把界面、NR等都搞的差不多，一直想学弄一个硬件来玩，群里有一大神前两年制作了小黑同学（天问离线语音模块ASRPro接入Homeassistant【超迷你】），我买了4个，非常很好用。现在业余闲着想学习开源硬件的东西。就想搞一个小黑同学可以用MQTT远程语音，但是大神太忙没空帮着做。我看了他们开源硬件，要焊那种小很0402的电阻，头都大了。年纪大，这么小的东西根本看不清楚的。
后面转换思路弄个开发板自己焊，就搞成了现在这样的。几个信息给大家，有要用的自己做，不难，费时间。
一、硬件
1、天问ASRPRO 2.0和 ESP8266都是开发板，双方就焊对接四根线；
2、喇叭是天问买时自带的。
3、外壳本来想打印，太贵，也不会设计，就找了好久现成的，回来打孔，太便宜大大小小买了好几个，看起来还不错。
4、为了外壳打个l喇叭孔和TYPE-C孔，十八般工具都用上了。
二、固件
1、修改了原ESPHOME配置，原来是2024版本的，最新ESPHOME 2026.08版有许多格式变化，不懂问AI。
2、顺便把原来订制的四个小黑的ESP都升级到2026.08版，顺便把IP写进去。由于家里设备太多，路由器静态地址不够分配。
3、天问编写与烧录与原来一样的。为了方便上下层对准，我改了原来的RX、TX GPIO 改成如下
uart:
id: asrpro_uart
tx_pin: GPIO1
rx_pin: GPIO3
baud_rate: 115200
parity: NONE
stop_bits: 1
rx_buffer_size: 512

图3：这家外壳比3D打印好很多2.15元/个。要选80mm*50mm*35mm 格式的，刚刚好！
