What is it.

@LynneB8898 It’s called a circuitboard

@LynneB8898 Ok.

A milled circuit board. Either single layer or double layer since you cannot make inner layers with milling. It's for an Atmega 2560. Which is the same microcontroller as the Arduino mega. I used it for some projects. It has many serial ports (UARTs).

Motherboard .

Unreal.

@pr0ud_americans Printed integrated circuit board. Common name PC Board 👍💯

@pr0ud_americans Fantastic.

CNC machine.

Awsome.

8-bit AVR micro controller with 256KB flash memory, 8KB SRAM, and 4KB EEPROM.ATMEGA2560

@aj_inapi crop circles, most will think circuit board

Micro chip

That's interesting.

Ruined!

Why was that so satisfying?

Its an atmega, 2560 model from from the looks of it

CNC router making a circuit board from copper sheathed insulation sheet.

@aj_inapi Machining of Traces and spaces for a Printed Circuit Board.

outdated old THT PC board, modern boards are SMT and require very little meat-labor -smaller -cheaper -produce far less heat - Create fewer "jobs" for worthless biological units

Used one back in college to prototype pcb [printed circuit boards] as minimum orders were on the 100's. I believe it's much easier to work without one today.

I used to have to etch my own with acid and a marker.

pc board prototyping. that was one of my jobs that I actually liked doing.

@XtexasgirlX Circuit board being masked by 2d printing before being put through acid to etch the circuit in the copper

Don't know precisely, but it's mezmerizing.

Its a play for pay world.

@baker_girlie Minimal electrical clearance

@gracieback2 ...

CNC router

Circuit board finishing around the traces and via holes. Removing the masking.

@SweetTexanRose PCB

As a technician, it is creating trace paths on a circuit board, saw that atmega2560 cpu marking as well.

a circuit board of some sort.

maga girls are the real super models, not nasa fakes 😉

An Arduino with an ATmega2560 Microcontroller, I use these in tons of projects such as the steering wheels on this sim rig 👇

Motherboard?

Solder mask?
