ESP32S3入手体验测试
- 🔖所入手的型号是
YD-ESP32-S3 N16R8
,该款和乐鑫官方推出的ESP32-S3-DevKitC-1
配置差不多。
- 🎈乐鑫官方介绍:ESP32-S3-DevKitC-1 v1.1
- 🔰两者采用的模组:ESP32-S3-WROOM-1 和ESP32-S3-WROOM-1U模组对比:
- 🍁
YD-ESP32-S3
和ESP32-S3-DevKitC-1
硬件基本信息:
- 🛠核心模组配置都是可选。两款开发板从原理图上看,板载WS2812b灯珠所连接的芯片GPIO引脚不相同。YD-ESP32-S3板载WS2812B引脚:GPIO 48 ESP32-S3-DevKitC-1板载WS2812B引脚:GPIO38
📑Micropython测试
- 📋YD ESP32S3 Micropython固件下载地址可以去官方也可以去YD官网下载,根据个人所使用的型号选择对应的固件。
-
📍YD固件提供地址:

-
🔨固件烧录采用乐鑫官方的烧录工具
flash_download_tool_3.9.5
进行烧录,烧录地址:0x0
,切记不要使用Thonny
软件进行烧录,它默认烧录地址是0x1000
。
固件烧录完成后,通过Thonny
软件,重启设备可以查看到打印的硬件配置信息。

from machine import Pin
from neopixel import NeoPixel
import timepin = Pin(48, Pin.OUT)
np = NeoPixel(pin, 1) # 一颗灯珠
np[0] = (10,0,0)
np.write()
r, g, b = np[0]
def handle_interrupt(Pin):np[0] = (0, 0, 0)np.write()time.sleep_ms(150)np[0] = (0, 0, 10)np.write()time.sleep_ms(150)np[0] = (0, 0, 10)np.write()time.sleep_ms(150)np[0] = (0, 0, 0)np.write()time.sleep_ms(150)np[0] = (0, 10, 0)np.write()time.sleep_ms(150)print("test-usr key")
p0 = Pin(0)
p0.init(p0.IN, p0.PULL_UP)
p0.irq(trigger=p0.IRQ_FALLING, handler=handle_interrupt)
- 🌿通过micropython查看硬件配置信息:
import machine
import esp
import micropython
# 打印堆栈大小
# print("堆栈大小:", esp.get_free_heap())
print("堆栈大小:", micropython.mem_info())
# 打印flash存储空间大小
print("flash存储空间大小:", esp.flash_size())
# 读取ESP32的唯一标识符
unique_id = machine.unique_id()# 将字节数组转换为可打印的字符串
unique_id_str = ''.join(['{:02x}'.format(byte) for byte in unique_id])print("ESP32的唯一标识符为:", unique_id_str)
- ⚡测试时需要注意:GPIO48引脚默认是没有直接联通到GPIO48引脚的,需要自行焊接一起。
