Farmduino 2.0a part list

Hardware
#1

Hello,

This is my first post. So apologize if I do something wrong.

I would like to set up a Farmduino board myself, but unfortunately I have not found a parts list for all the electronic parts. So I searched all parts of the circuit diagrams.

However, there seems to be an error with the filters L2 and L3. The information there is: 60R, 100MHz, 0805. That makes no sense for a filter. Could someone from Farmbot correct that, please?

Or could someone post a high-resolution photo of his Farmduino that shows the labeling of these parts?

Best regards from Germany,
Klaus

Hello Paul,

I bought https://www.reichelt.de/emi-suppression-filter-smd0805-blm21-60-ohm-blm21pg-600-p89686.html?&nbc=1 and it works.

An alternative seems to be: https://www.mouser.de/ProductDetail/Murata-Electronics/BLM21PG600SN1D?qs=%2Fha2pyFaduhH0aAu7ZFdEOSblDW%2F6RtolvaEgR2ERZXjzE%2BFqBnF6Q%3D%3D

The description in the farmbot doku is not really sufficient.

BTW: be careful with the Voltage Regulator TPS543X. The X is not a joker for any digit. It must be the TPS5430. E.g.: https://www.mouser.de/ProductDetail/Texas-Instruments/TPS5430DDAR/?qs=zwk82MlA57ZJdOTovH1aYA%3D%3D
My first trial ended in a cloud of smoke.

And one other hint: as encoders I’m using
https://www.mouser.de/ProductDetail/630-AS22-M530-5G12 or https://www.digikey.de/product-detail/de/broadcom-limited/AS22-M530-5G12/516-4000-ND/8509622

These encoders didn’t have the correct hole but I used a 6mm brass pipe with 0,5mm wall thickness from my local hardware store as an adapter. Most NEMA 17 motors have 6mm axis It’s working! Don’t forget the fitting plugs: https://www.digikey.de/product-detail/de/SHR-08V-S-B/455-1383-ND/759872/?itemSeq=347973860 with https://www.digikey.de/product-detail/de/SSH-003T-P0.2-H/455-2963-1-ND/5725854/?itemSeq=347974107

The advantage of this part is that it is available in small numbers of items.

Best regards,
Klaus

Some other observation I made, I described here: https://forum.farmbot.org/t/farmduino-documentation-bug/7030/5

wow thanks for the fast response Klaus! I will defintely consider your findings for my PCB prototype assembly.

I stumbled across another component: The capacitor for items C8, C9, C10, C11, C12 is specified as 100uF, 35V and footprint of 5mm (diam.) and 5.3mm (width, length). I did not find any components that meet this footprint, just larger ones. Which cap did you use here?

where are you guys opening these files? Are you using Altium Designer? I managed to generate gerber files but am yet to receive confirmation from a local pcb manufacturer as to whether they are of any use.

Hello Paul,

I used https://www.mouser.de/ProductDetail/Panasonic/EEE-FN1V101XP?qs=sGAEpiMZZMvwFf0viD3Y3a3yb5D6sPUgaPTazj2%2BI5gFiJiLUXMNTQ==
Another source should be https://www.reichelt.de/elko-smd-100-f-35v-105-c-low-esr-vf-100-35-k-d8-p84762.html?&trstct=pol_0&nbc=1

Thea are perfectly fitting. I measured the diameter from the pictures in the farmbot store.

Best regards,
Klaus

Hello pandaero,

yes, I created a virtual windows machine and installed the demo version of Altium designer. The precedure to export Gerber Files is described here: How to export Altium PCB to gerber files - JLCPCB: Help & Support

Maybe I was just lucky, but it worked right the first time.

Best regards,
Klaus

It worked! Thanks :smiley: Now I’m struggling to create a bill of materials (BOM) with specific MFG codes.

@pandaero you could create the so-called Active BOM within your Altium project to store manufacturer and supplier information.
