Voltage Regulators Group Buy


(Brendan Halliday) #1

Hi folks,

I’m looking to buy a bunch of small voltage regulators to have on hand for various projects.

Specifically, these:

These voltage regulator boards have both adjustable and fixed voltage ranges available, are stupendously easy to place on a PCB or in a circuit and as an added bonus have an enable pin so you can switch them on and off. These would be useful to pretty much any member doing ELV electronics and could be quite useful for people wanting to run projects off decently sized batteries.

They report needing at least 12V, but I suspect they may work fine down to 5v.

I’m going to be buying 100, by the end of this week. If you’re interested in jumping in, it’ll be $1 each for each one. Please let me know if you’re interested in this thread ASAP as if I don’t get interest I will order by Thursday.

  • 100 for nog3
  • 20 for Hovo
  • 20 for Pelrun
  • 5 for Jabelone
  • 50 for Crofty
  • 10 for Rosa
  • 30 for devians
  • 20 for Mick
  • 5 for Riumplus
  • 20 for Catprog

Current total: 280.

Can I grab 20?


(James Churchill) #3

Put me down for 20 too.


(Jaimyn Mayer) #5

Put me down for 5 please. I’ll probably use one for my e-ink name badge :slight_smile:


(Aaron Bycroft) #6

50 for me please


(Brendan Halliday) #7

First post updated with current list of people who’ve contacted me to buy some.


(Mike Morrison) #8

Could I get 20 please


(Mike Ando) #9

Put me down for 5!


(Brendan Halliday) #10

First post list updated. I’ll be purchasing these on Tuesday (23 July) night


(Catprog ) #11

Do they have ones that go even lower?


(Brendan Halliday) #12

These ones support down to 1.8v. Any lower than that and you’re probably looking for voltage references.


(Catprog ) #13

Put me down for 20.


(Brendan Halliday) #14

Just a heads-up, I will be making this order tonight after 8PM so get your orders in by then.


(Brendan Halliday) #15

These have arrived, come find me Tuesday night to collect.

May paypal address is nog3@nog3.net if people would like to send it that way, but I can also take cash and bank transfers.
