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~!
ah that sounds ok.
one other thing,
would it be possible to add a 4pin header (+v,gnd,io1,io2(digital io)) for the ultrasonic sensor??
as adding this port will make it perfect for use out the box with Nybble.
