ESP32-Ethgate

This is a basic ESP32 (ESP32-WROOM-32 module) with LAN8720A PHY project intended to work mostly as an ESP-NOW to (wired) MQTT gateway. CH340C-based USB is included.

It designed to be produced in my PCB mill. If your PCB mill can handle QFN32 footprints and double-sided PCB’s then you might be able to duplicate this.

For simplicity, it uses the GPIO17 PLL clock technique rather than the GPIO0-based crystal, and includes a second 3.3v regulator to control the entire ethernet power rail independently. It still needs USB power, although at some point I might take a stab at a PoE version.

The Arduino-ESP32 ETH_LAN8720 sketch should work with the following configuration:

#define LED_BUILTIN 2	// or use a NodeMCU-type of board definition #define ETH_CLK_MODE    ETH_CLOCK_GPIO17_OUT #define ETH_POWER_PIN   12 #define ETH_TYPE        ETH_PHY_LAN8720 #define ETH_ADDR        1 #define ETH_MDC_PIN     23 #define ETH_MDIO_PIN    18  ETH.begin(ETH_ADDR, ETH_POWER_PIN, ETH_MDC_PIN, ETH_MDIO_PIN, 	ETH_TYPE, ETH_CLK_MODE) 

I flash mine with the ESP32 clock set at 80MHz, which seems to be more stable at 100Mbps connection speeds and draws approximately 25% less power.


ESP32 Ethgate

这是一个带有LAN8720A PHY项目的基本ESP32(ESP32-WROOM-32模块),主要用作ESP-NOW到(有线)MQTT网关。包括基于CH340C的USB接口

它是为在我的PCB工厂中生产而设计的。如果你的PCB工厂可以处理QFN32封装外形和双面PCB,那么你可能可以复制它

为简单起见,它使用GPIO17 PLL时钟技术而不是基于GPIO0的晶体,并包括第二个3.3v调节器,以独立控制整个以太网电源轨。它仍然需要USB电源,尽管在某个时候我可能会尝试PoE版本

Arduino-ESP32 ETH_LAN8720草图应与以下配置配合使用:

#define LED_BUILTIN 2	// or use a NodeMCU-type of board definition #define ETH_CLK_MODE    ETH_CLOCK_GPIO17_OUT #define ETH_POWER_PIN   12 #define ETH_TYPE        ETH_PHY_LAN8720 #define ETH_ADDR        1 #define ETH_MDC_PIN     23 #define ETH_MDIO_PIN    18  ETH.begin(ETH_ADDR, ETH_POWER_PIN, ETH_MDC_PIN, ETH_MDIO_PIN, 	ETH_TYPE, ETH_CLK_MODE) 

我将ESP32时钟设置为80MHz,这似乎在100Mbps连接速度下更稳定,耗电量大约减少25%
