Re: Release of version 2.0 of ABS solution for QMX+ (Automatic internal antenna tuner, internal battery and internal speaker with audio amp) #PSU #QMXplus #audio #ABS #ATU


 

Fellow hams,
?
Couple of updates.
?
1. To ease the access to the GitHub repository I made a URL forwarding: .
?
2. I made a simulation of JLCPCB order to see what the most unoptimized cost could look like (no coupons, no large order discounts). Simulation was per minimum possible 5 set of PCB order.
?
So, the total with all shipment/taxes per build comes to around 111$-115$. Which is 10$ higher than per V1.2 build. Which is excellent considering 6-Layer V2 ATU PCB with Electrolyses Nickel Infused Gold plates (ENIG) and other V2 improvements. While 6-Layer PCB has increased the cost, the reductions comes from multiple sources, like JLCPCB's own recent reduction of 6-Layer PCB's, schematic simplification of ABS V2 (elimination of ATMEGA), most of audio amplifier components are SMD's. So, at the end cost balances itself.
