Farnell/RS order codes

Hi All,
I recently made up a couple of kits for some collaborators, which mostly consisted of the Raspberry Pi electronics. In case it’s useful to anyone, I’ve pasted the part numbers below:

Item Value Farnell Order Code RS Order Code
Raspberry Pi 4, 4Gb £44.36 SC15185 182-2096
USB to GigE Adaptor £14.70 CS25041 195-4911
Ethernet Cable £0.68 1526203 333-6469
USB-C Power Supply £7.07 SC15241 187-3412
SD Card £6.13 3410199 186-4648
Micro-USB Power £6.59 SC14154 177-0222
HDMI-micro-HDMI adaptor £2.35 SC15240 197-3419
USB A-C cable £2.81 CS29710 182-8848
USB A-microB cable (short) £2.50 CS22611 182-8870
USB A-microB cable (1m) £1.15 2468266 182-8495
Raspberry Pi Camera £19.10 ? 913-2664

That list includes options for using the Pi directly (micro-full size HDMI adapter) or for using an ethernet cable (incl. USB adapter in case your laptop no longer has an RJ45 port). It also includes both international wall-plug power supplies and USB cables to allow the use of a power bank. I’ve assumed you’re using a (micro-USB) Sangaboard v3, hence the extra USB cables and two power supplies. You can buy the Pi Camera from Farnell - they were just out of stock when I made this list. Prices are from Farnell, in the UK, though they may include educational discounts and don’t include VAT.

For the components in the “bag of bits”, I used the suppliers below. If you’re in the UK, this can be obtained from OpenFlexure Industries but we’re not yet shipping internationally. Unfortunately, that includes the EU for now - don’t get us started :frowning:

  • Westfield Fasteners for all the screws/nuts/washers
  • Simply Bearings for the Viton bands - because they are a University supplier. For OpenFlexure Industries, we prefer Eastern Seals as they give a more detailed spec and are significantly cheaper.
  • AliExpress for the plastic condenser lens - see the thread on sourcing non-printed components for some links. These tend to stop working after a while so I won’t duplicate that here.

The tube lens is most easily obtained from ThorLabs, and the LED can also be had from one of RS/Farnell - only one of them stocks the exact model we use, but if you’re not too fussy about colour reproduction, any 5mm LED will give you an image.

Hopefully, in the not too far distant future OpenFlexure Industries will have enough cash on hand to buy a stock of tube lenses which will make things easier for those in the UK.

We are still in active talks with others that may soon start selling kits in the USA and elsewhere. We also hope that once everything has settled down OpenFlexure Industries will be able to ship to Europe. However, first we have to understand the implications of such small scale export within the unmitigated disaster that is Brexit. If anyone in the EU want to start selling kits so we don’t have to, please let us know!
