Very cool little module.

I spent four hours trying to get this to work the first day and eventually gave up. When I tried to return it, I discovered it was listed as having hazardous chemicals, or something like that, and couldn’t be returned. It’s just a microcontroller and LCD screen—ugh. I then reached out to WaveShare, and they sent a PDF of the same information I’d already found on their Wiki. After another four hours of trying, still nothing. I want to understand why it’s not working, especially if it’s something I’m doing wrong—that knowledge is more valuable to me than the item itself. Unfortunately, the only follow communication from WS is the company is on holiday.I also noticed there are zero reviews, which I’ll take as a red flag moving forward. As a side note, I tried contacting Amazon, but I kept getting stuck in a loop, with the message that the item is non-returnable. I’ll chalk this up as a $20 lesson on WaveShare and Amazon customer support. I’m not upset, just a little frustrated by the wasted time. Mostly, I’m curious if reviews are being deleted or if this just slipped through the cracks. Either way, this experience will serve as a warning to others.Update:Although I do not feel i can change the rating of the product I wanted to update the review of the company. They reached out and apologized for the defective device, thanked me for advising them of the misclassification of the device as hazardous preventing a return, and refunded my money. They also are willing to continue working with me to fix the problem and if it turns out to be a defective product they will replace with a new working device free of charge. I probably will decline any further wasted time on this but will not hesitate to buy from WaveShare again. I am likely going to by the esp32s3 model which is the upgrade. If I find out there is a fix or that I was doing something wrong and the item works I will edit the review. My hope is that someone that got the device to work will post a review, but for now im the one and only review.EDIT:This product has been re-categorized as nonhazardous and so can be returned. Waveshare has worked with me to make the original work. I am glad i learned things and that I was able to work with Waveshare who has proven that they are committed to customer satisfaction. They have room for improvement still. I will not hesitate to buy from them again.

Good

Instead of using the Waveshare examples I just loaded up the demo from the Adafruit_ST7789 library. I have seen others online complain about the display always remaining black. All that I had to do was bring the backlight pin GPIO_22 high and the display lit up right away. This pin can also be tied to 3v3 if you like to always keep the backlight on. The display size is small but it is clear and easy to read. I will buy again if another project needs this form factor.

This is a super fun dev board to mess around with. It is quite capable for it's size, the onboard screen is nice and clear and the documentation is adequate.

This Waveshare ESP32-C6 development board is a fantastic platform for a wide range of projects. The integrated 1.47-inch display with 262K color delivers crisp and vibrant visuals, making it ideal for interactive applications. The ESP32-C6 processor, with its support for Wi-Fi 6 and Bluetooth Low Energy, provides excellent connectivity options. The colorful RGB LED and various onboard peripherals offer further flexibility for customization. I've found it to be a powerful and versatile board that simplifies the development of IoT and other connected projects.
