New NyBoard Prototype

This is the new Nyboard prototype, and I made the design.

After several errors I made, the new prototype made its first SMT production ( Keys and pins are soldered by band )

Characteristics:

CPU: Xtensa LX6 Dual core 32bit @ 240MHz, much faster than ATMega328P@20MHz

user RAM: About 400KBytes

user Flash: 16MByte SPI flash

Bluetooth: On board BLE 4,2 and EDR ( EDR without Arduino support )

WiFi: 802.11n@150Mbps, on-board antenna

IMU: ICM20600 6-Axis accelerator and gryometer

PWM channels: 12 PWM channels

I2C: 1 I2C port

Serial: totally 2, one in 2.54pin, another connected to CP2102 USB-Serial bridge.

USB: in Type-C model, use Serial (Serial 1)

IR control: 1 HX1838B IR sensor

Analog: 4 channels 12bit ADC, include 1 16bit SAR high precision ADC

DAC(Digital to Analog Converter): one 8bit, connect to PAM8302A mono channel audio amplifier

Audio: 2-pin 2,54, with DAC data/WAV file/MP3 File playback!

Now we're working on port ATmega328P program to ESP32. Please standby.

Another 2 small kit for Nyboard V0 users:

HC-05 bluetooth wireless serial with downloader adapter

ESP-01s wifi adapter

I wonder how can I express them to you with cheap mail fees...

Or I will write a new post to tell you how to DIY them...

Thanks~!
