Thought I would share my ESP32 project that uses the Finnhub API to grab stocks or crypto pricing to display on a 1.69" lcd. The hardware used is the ESP32-S3FN8 processor, 1.69" TFT using a spi bus and just need a free Finhub account and stock or crypto stickers. This will be an open source project...

Thought I would share my ESP32 project that uses the MLX90640 thermal image sensor. The hardware used is the ESP32-S3FN8 processor, 1.69" TFT using an 8-bit bus for fast refresh rate and the MLX90640 controlled by i2c. This is an open source project with full parts list, code and Altium Design files...

The slowest upload speed has not fixed the issue.

My ESP32-S3 will not upload and Arduino sketch using the CP2104. I double checked the Rx Tx lines from the S3 to the CP2104 and have a 10K pull-up on IO0 but none on IO45 that I believe is correct. Attached is the schematic and upload errors. If anyone has any idea, it would really help. I find it o...

Uploading sketches and serial data worked so intermit and poorly for me that I ended up adding a CP2104 usb chip. After that it all worked perfectly. I was hoping after a few updates it would work better but nope.

Not sure if this will be of help or not but I have my esp32 reading temperature and humidity from an Aliexpress beacon: https://twitter.com/mikerankin/status/1 ... 2578297856

Very nicely done! Thank you for posting your code as well. Next time I need to log data I'll checkout your code.

This is a ESP32 based color E-INK display that wakes up every 15 minutes, grabs local weather data, formats and shows it on the display and then goes back to sleep. No idea how long it lasts on a tiny lipo battery yet but it's been running for a few days now. Sleep current is around 30uA or so. The ...

I'm having trouble with the Arduino deep sleep with timer wake up example code. On my hardware I've added a little led that is supposed to blink every 10 minutes. Right now it will wake up and blink for a few hours and then stay sleeping forever. The battery voltage remains fine during the entire te...

Another PCB revision is on the way that should allowing it to be powered from a battery. Right now it can only be powered using a microUSB cable. The e-ink displays are 2.13" in siz...
