GPIO current drawn The absolute maximum current drawn per GPIO is source 40mA and sink 28mAmp according to the “Recommended Operating Conditions” section in the ESP32 datasheet.
Usually I use LDL1117 to replace AMS1117, which solves all these problems. It's an excellent LDO, but its pinout is not compatible with your board. As a stopgap, before changing the LDO, you can put a few hundred µF low ESR electrolytic cap on the output. Note in the ...

Seeed Studio XIAO系列是小型开发板,共享类似的硬件结构,尺寸实际上是拇指大小。这里的代号“小”代表它的一半特征“小”,另一半将是“羊角面包”。 Seeed Studio XIAO ESP32S3 Sense集成了摄像头传感器、数字麦克风和SD卡支持。结合嵌入式ML计算能力和摄影能力,这款开发板可以成为您开始使用智能语音和视觉AI的绝佳工...
Assign the correct pinout depending on your ESP32 dev board There are several development boards based on the ESP32 chip, make sure you assign the correct pin numbers to the signals that interface with the TFT display board. Its recommended to use a predefined configuration below, but you can...
(any 2 colours) to reduce the RAM needed. On an ESP8266 the largest 16-bit colour Sprite that can be created is about 160x128 pixels, this consumes 40Kbytes of RAM. On an ESP32 the workspace RAM is more limited than the datasheet implies so a 16-bit colour Sprite is limited to ...
After the LAN8720 chips got available again, we decided to make a new board revision. These are the current boards. We used the ESP32-WROVER module, for additional 8MB PSRAM and 16MB Flash. We also added an SD-card. Unfortunately, we used the wrong pinout, make it very difficult to ch...
