Mini Attiny Board *updated* With Programmation

IMG_0330.JPG

Since several month i read forum about Attiny and Arduino .
It's a great platform for MAKER
So i decide to make my own board for Attiny85.
It's a low cost version of Arduino

The Shema

I made the shematic with Eagle

The PCB

I ordered PCB with OSH Park

they make a good job

for less $9.00 you have 3 board with free shipping.

List Part

R1: 10Kohm
R2: 220 ohm
C1: 10 ùF 50V
C2: 0.1 ùF On Ebay
S1 : micro switch pcb 6x6x4.5
U1: Attiny85 , but Attiny45 works
IC1 : LM7805
JP3,JP5,JP6: Pin header black
JP2: Pin header red On Ebay
JP1: Pin header yellow
J1: Pin header double row

Program the Board

My experience:

to program the board you need an arduino uno R3

First Connect the attinyboard isp header on the Arduino board

  • MISO on pin 12 arduino
  • SCK on pin 13 arduino
  • RESET on pin 10 arduino
  • MOSI on pin 11 arduino
  • Vcc on +5v
  • Ground on ground (!!!)

upload the sketch " arduinoisp" on your arduino board

select the good board and port for that.

now your arduino is as ISP

Change the board to attiny

Upload your sketch or for example the Blink sketch

Enjoy !

A good tuto here :

New project : make an adapter to program the board with arduino

To Be Continued !

It's my first instructable

The next step :

make a Lipo charger with smd : The board is ordering:

perhaps with a solder stencil :
