ideaspark® ESP32 Development Board Integrated 1.14 inch ST7789 135x240 TFT LCD Display,WiFi+BL Wireless Module,CH340 Driver USB Type-C for Arduino Micropython (ESP32 1.14 inch LCD(Solder PIN))

Great product works just as advertised! Fun and easy to use!

This is a very capable little Espressif ESP32 microcontroller with a beautiful ST7789 based screen. Download the Adafruit ST7789 support library, and the Adafruit GFX library and you can draw photos, or programatically render text or geometric objects, like the little balls I made to bounce around in this video. Little computers are so fun to work with... kind of like home PCs from the dawn of the era. Dive in and imaging yourself coding on an ancient Apple II computer back in the early 1980s. These little things are many orders of magnitude more powerful than those old home computers were though, of course.

So far this board has worked out well for me, however at a certain point I got sidetracked until noticing that my D33 pin and D25 pin were electrically reversed according to the serial monitor. I would have to physically connect to D25 and code to D33, or vice versa. Not familiar enough with these to know whether that random ADC goof can happen somehow and can't confirm if it was just always like that from the start.

This board uses the ESP32-WROOM-32 rather than something more robust like the esp32-s3, which means that aside from other limitation the implementation of the serial to USB function inst fully native to the chip and does not have direct access but acts as a sort of pass through. This mean that anything that needs direct access to the Serial/USB function like running a badusb/bashbunny/rubberducky firmware will not work. Although the device has 3 buttons you really can only use 1 of them, the others are just reset button for the screen and boot button and there is no way through code to alter this behavior. As others have stated you cannot power this from a USB-C to USB-C you must use a USB-A to USB-C cord. If these limitation are not an issue for you and you just want a simple ESP32 for learning or prototyping this is a good enough board but I would recommend going for something with better support and documentation. The build quality seems good but not perfect the screen on min isn't aligned square to the board and caused issues when making a 3d printed case for it. It does have a battery connector but it does not seem to "just work" when you plug a battery in maybe this is how all ESP32s work and you need to code for it but you cannot just plug the battery in and expect it to charge or even get power from the battery. The screen size is a bit on the small side and there are other boards out there with bigger screen for around the same price I would save my money and get a better board.

The 1.14 inch ST7789 135x240 description has the pinouts but they are kinda hard to understand... Here they are in a copy/paste format: // Define the IdeaSpark specific pins #define TFT_MOSI 23 #define TFT_SCLK 18 #define TFT_CS 15 #define TFT_DC 2 #define TFT_RST 4 #define TFT_BL 32

Fun little device at a great price!

This board is improperly engineered and missing the resistor needed to use a cable that has USB-C on both ends. This means for instance that you cannot plug it into a MacBook with USB-C. It won't power on. The designer did not follow the USB-C specification.

Performed as expected. Wanted an easy dev board with a screen present. The directions for arduino was rather simple and easy to hook up. From opening box to having an image on display only about a half hour.
