[DigiKey "Smart Manufacturing, Non-stop Happiness" Creative Competition] Material Unboxing Multi-channel Titration Controller Based on OpenThread [Copy link]

##ForewordSince I received the email very late, I saw the date and thought it was not selected, so I didn't read the email. I saw the email 2 weeks later, which was basically the last time I placed the order and received the goods. After placing the order, I filled in the company address, and the US side went through various audits, and there were more than 10 emails back and forth. Here I suggest that DigiKey can list all the problems at once. ## Things I bought this time|Project|Function| |--|--| |Raspberry PI 4B 4G|For IoT edge computing| |Raspberry PICO|For quick verification of early code, and it may also be used to control TMC2209 and drive plunger pumps| |ESP32-C6 evaluation version|For developing Thread-based terminal devices| |ESP32-C6 Mini module|Add wireless control function to plunger pumps. I originally wanted to buy H2, but found that it was out of stock, so I used C6 instead. Since the size is a little bit required, I chose a non-stamp hole package|

The packaging of the Raspberry Pi board is a bit weak, just a thin one. Now the cost performance of the Raspberry Pi is getting lower and lower. With the SD card, it is almost enough to buy an N100 x86, which has more than twice the performance. Adding a USB to GPIO module can also realize the functions of the Raspberry Pi. But the advantage is that many companies' DEMO projects are based on it, which is convenient for early rapid evaluation and testing.

I picked up a shell on Taobao for more than 10 yuan, including a fan, 3 heat sinks, 1 HDMI cable and 12V5A voltage. This price is simply amazing. But after buying it, I suddenly remembered that the Raspberry Pi 4B has 2 HDMI outputs, and I should add another line. On the right is the evaluation board of ESP32-C6. Espressif's packaging is getting better and better now, which is very friendly to me who puts it everywhere. Often various boards are piled together, and when turning over, various pin headers are bent and patches are damaged. The box can just put the PICO board in it at the same time. Lessons learned: When soldering the PICO <img src="//bbs.eeworld.com.cn/data/attachment/forum/202311/08/220756hpbjvv4gdzzvrjer.jpg.thumb.jpg?rand=8827.795208573843"onclick="zoom(this, this.getAttribute('zoomfile'), 0, 0, '0')" zoomfile="//bbs.eeworld.com.cn/data/attachment/forum/202311/08/220756hpbjvv4gdzzvrjer.jpg.thumb.jpg?rand=8827.79" file="//bbs.eeworld.com.cn/data/attachment/forum/202311/08/220756hpbjvv4gdzzvrjer.jpg.thumb.jpg?rand=8827.79" inpost="1" onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})" lazyloaded="true" initialized="true">

,
 remember to solder the three SWD PIN sockets on the front, otherwise it will not fit into the breadboard.
