Hi All,
I'm opening up the V4 stepped attenuator & preamp controller for pre-ordering. Here's how the pre-ordering is going to work.
1) You can pre-order a V4 starting today, March 25.
2) You don't have to pay in full when you place the pre-order BUT you do have to pay a $50 refundable deposit.
3) There is no firm/estimated release date yet - May/June is achievable and I'm working towards that but no promises
4) Orders will be shipped in the order they came in - so FIFO (first in, first out).
5) When it's time to ship your order, you'll receive an invoice for the remaining amount due.
6) If you change your mind, your order will be canceled and the $50 deposit will be refunded in full.
The V4 product page is set up so that the default scope is: 1) a V4 board, 2) an LDR module, 3) an OLED display assembly, and; 4) an Apple compatible remote. You can opt out of items 2, 3 and 4 if you already have these items but you will need them. The OLED display assembly includes infrared receiver and encoder plus cabling. A 5V power supply is NOT provided but minimally you can power the V4 from any Micro-USB cable.
Any existing quad LDR Module from your V3 board will work with the V4.
Most older OLED displays (Rev C or later) will also work with the V4.
An existing silver/metal Apple remote will work with the V4.
