The ESP-01S usually has a 4MByte serial flash fitted - 4x bigger than the ESP-01.The ESP-01S is more reliable than the ESP-01, as pull-ups ensure that no random signals can get to RST or CH_PD.The single pull-up on the GPIO0 pin allows easy push button operation.The...
you have an ESP-01. The Blue led on the ESP-01 is driven by the TX (GPIO1) pin and normally just flickers when your are sending data on the Serial connection. However if you are not sending any Serial (debug) data, you can
The following figure illustrates the ESP8266 12-E chip pinout. Use this diagram if you’re using an ESP8266 bare chip in your projects. Note:not all GPIOs are accessible in all development boards, but each specific GPIO works in the same way regardless of the development board you’re usi...
1. esp32开发板安装包 开发板管理器中,搜索esp32,安装2.0.13版本(需要安装2.0.16之前版本,不然不匹配tft_eSPI库,程序会重启)。 img 2. 安装tft_eSPI库 2.1. 驱动库安装 库管理中,搜索tft_eSPI,安装最新版本2.5.43。 img 2.2. 库代码修改 这里需要修改引脚代码,适配st7789驱动。 (1)打开User_Setup.h文件。
You can provoque a reset of the card by a rising edge on the RESET pin. Diagram Below, you will find the diagram circuit for flashing the EPS01, with an external power supply and a USB-Serial converter. Remarks: the resistors are optional ...

If the ESP32S3 mainboard only has a USB port, you need to enable USB CDC, as shown in the following diagram: Compile and upload the program: ①. Compile the program; ②. Compile and download the program; ③. Download successful. Open the Serial Monitor window, and the demo will ...
Since all GPIO pins of the XIAO ESP32S3 are assigned their own functions, we do not have a GPIO configured for the battery pin. this means that we cannot get the battery voltage at the software level by reading the analog value of one of the GPIOs. If necessary, you can consider conn...
This is the diagram. LED connected to GPIO1 does not appear in the diagram. I hope you can help me. Thanks. Re: ESP-01 + BMP280#92294 ByVossing-Fri Sep 10, 2021 2:31 am I want to make this too, have you found a solution ?
