ESP32 Module Schematics and Board Files

Espressif teased about their ESP32 WiSoC with WiFi and Bluetooth LE a few weeks ago in a letter addressed to developers, but did not release that much information. The company has now released some documents in the forums (registration required) concerning ESP32 module  including PCB processing requirement, schematics and PCB layout, and bill of materials. The very first modules will actually be based on ESP31 processor, which only slightly differs from ESP32 with some swapped pins. The BoM is pretty small with several capacitors and resistors, one inductance, a 26 MHz crystal, ESP31, and a Gigadevice flash. The schematics have been designed with Orcad 16.6, so if you don’t have the program, you can read the schematics with Orcad 16.6 Lite, which is free to download. I’ve also printed the schematics to a PDF file.  I’m not sure how to open the .pcb file which should be the module’s PCB […]

Espressif ESP32 Dual Core SoC Features Faster WiFi, Bluetooth 4.0 LE, and More Peripherals

Espressif teased us about a successor to ESP8266 a few months ago that would support both WiFi and Bluetooth Low Energy, and John Lee, working for Espressif Systems, has now sent a letter to ESP8266 developers announcing the new wireless SoC with two Tensilica L108 cores and called ESP32. Espressif ESP32 key improvements over ESP8266: Faster WiFi – Wifi has been upgraded to support HT40 speed (144.4 Mbps) and has a new RF architecture to simplify the application schematics Bluetooth Low Energy and Classic Dual core processor – 2x Tensilica L108 processors clocked at up to 160 MHz Low Power Mode Improvements – ADC conversions, level thresholds, etc.. can now be performed in deep sleep Peripherals – Capacitive touch, ADCs, DACs, I2C. UART, SPI, SDIO, I2S, RMII, PMW, etc… but no USB. More RAM – ~400 KB on-chip RAM Security – Hardware accelerated AES and SSL, and more undisclosed improvements. […]
