1、模块原理图 MINI_V3 黑白原理图上有相关资料 模块原理图如下图所示: 2、按照一般教程接线,注意VCC为3V,UTX接USB转TTL串口的RXD引脚,PB8连接1K欧电阻到esp8266 的CHIP_EN脚(板子上已经有),当PB8接3.3V时,芯片正常工作。芯片的GPIO0为工作模式选择引脚,开发板上对应的是P... ...
The ESP12-E NodeMCU Kit is one of the most used ESP8266 development boards. It features 4MB of flash memory, access to 11 GPIO pins, and one analog-to-digital converter (ADC) pin with 10 bit resolution. The board has a built-in voltage regulator and you can power up the module usin...
10.3 申请设备ID 购买设备ID:使用 ALINK SDS 的每一个设备都需要一个唯一的设备ID,设备ID需要向阿里官方购买。 烧录设备ID:设备ID需要在产品生产时烧录到设备的eFuse中,为方便您的修改,在产品开发时,您可以先设备的ID直接烧录 FLASH 中,我们为您提供了生成设备ID固件脚本,请按照如下说明操作: 填写设备ID列表:打...
This is ESP8266 chip with 1 CPU cores, WiFi, silicon revision 1, 4MB external flash Restartingin10 seconds... peripherals/uart_echo 这个项目用于演示ESP8266对于UART0的串口数据接收和发送. 因为UART0就是用于烧录板子的串口, 所以烧录后, 直接monitor就能进行操作. ...
