Is there a circuit diagram for the ultrasonic PCB?

[wolfch]

I ordered a small run of your Cing ultrasonic printed circuit boards from:
https://www.pcbway.com/project/shareproject/I2C_Ultrasonic_sensor_with_compensation.html

The silkscreen shows parts placement, but do you have a schematic (circuit) diagram?

Also I noticed the code is for Arduino which is normally Atmega328, but this sensor board uses ATtiny84, so do you use ATmel Studio or the Arduino IDE to program the ATtiny84?

Thanks

I found the schematic under Hardware/Schematics but I needed to install Eagle to open and view it. Still wondering about which tool to use to compile & program ATtiny84

Hello, I can send you one. I used USB ASP to flash Attiny84 using arduino. You can download Cing board manager to arduino to have Attiny84 in Arduino. You can also use Arduino Uno insted of USB ASP.

Here I am posting a schematic with pick and place diagram with values.
