The MarcDuino v1 is a DIY board. In most cases, you’ll need to build two boards: a Master and a Slave. The two boards are identical. The only difference is the firmware that’s loaded on each.<\/p>\n\n\n\n

Order the materials from the materials page here<\/a>. Be careful to order enough components for two boards.<\/p>\n\n\n\n

Assembly<\/p>\n\n\n\n

\"V1<\/figure>\n\n\n\n

Solder the components according to the silk screen and the picture above. Order is unimportant. <\/p>\n\n\n\n

4 components are polarized:<\/strong><\/p>\n\n\n\n

– the 100 uF capacitor, vertical stripe on the side indicates the (-) pin<\/p>\n\n\n\n

– the two LEDs: note where the flat side is and align to markings on the board (no flat side? See note 2 below!)<\/p>\n\n\n\n

– the ATmega328p chip: position the half moon  notch as shown on the board.<\/p>\n\n\n\n

*WARNING* There is a second 1k resistor at the bottom left under the green LED, not shown on this picture!<\/strong><\/p>\n\n\n\n

– I forgot this 1k resistor on the v1.0 board, and added it back in the v1.1. Don’t forget it! It’s drawn on the silk screen.<\/p>\n\n\n\n

*WARNING* Make sure to solder the right lead of the first 1k resistor (at the top) into the PC3 hole, past the headers!<\/strong><\/p>\n\n\n\n

 – In the PC3 hole like in the picture above. NOT in the PC4 hole! The silk screen is confusing as it looks like it stops on the wrong hole.<\/p>\n\n\n\n

I make the 3 pin wide servo blocks by using a combination of a 2 row and a single row strips<\/strong><\/p>\n\n\n\n

– I hold them together in place temporarily with a servo 3 pin connector plugged in while I solder.<\/p>\n\n\n\n

The flat side LED marking is hard to see on the boards silk screens<\/strong><\/p>\n\n\n\n

– <\/strong>both LEDs flat sides (negative) are oriented towards the bottom of the board (towards the edge that says MarcDuino).  <\/p>\n\n\n\n

Some cheap Chinesium LEDs ship without a flat side or with the flat side on the wrong side (!)<\/strong><\/p>\n\n\n\n

–  Use the shorter pin or the wider post as the indication of the flat side (negative), as shown in the diagram below.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Upload the firmware<\/p>\n\n\n\n

Firmware upload is the trickiest part of the build. Follow every step carefully as explained in the Firmware Upload page<\/a>.<\/p>\n\n\n\n

Next steps<\/p>\n\n\n\n

After you have uploaded the firmware and got the little LED blinking, you need connect your boards<\/a>, install your radios<\/a>, and start playing with it with R2 Touch<\/a>. If you want to, you can also test the functionality of your MarcDuino without a radio nor R2 Touch by connecting it directly to a computer through a serial port as explained here<\/a>.<\/p>\n\n\n\n

Make 3D printed mounts<\/p>\n\n\n\n

Optionally, you can also make 3D printed mounts<\/a> for your boards.<\/p>\n","protected":false},"excerpt":{"rendered":"
