Thus the code runs on the - bluetooth part unlike all our other designs. - - swrr072 is a USB dongle design that shows use of a Johanson integrated balun - that's 0.68 at q100 with a pcb trace antenna on 2.4ghz .. pcb is 4 layers - and 1.616 x 0.632" .. looks like I could take the RF end of the design as is - for the 2.4gzh end. Maybe make the board wider to fit some hammond box? - - using a Hammond 1591XXMTBU or 1591XXLTBU, could put the 2.4ghz antenna on - one of the long sides, and UHF SMA and USB+power switch on opposite small - sides?

The box - boss height is specified as 4mm, so that fits in a purely vertical sense, - but I'm worried about the box wall to base radius, and the fact that the - box walls aren't exactly vertical. - - Hammond doesn't specify the radius between the wall and base of the 1551K - box. Given other things they do specify, it might be that 1 mm is a - conservative guess. The specification for the inside dimensions of the lip - around the lid is 10 mils smaller than the max PCB dimensions, and it *looks* - like that inside edge might be about where the wall radius ends. The drawing - shows the lid inside as 6.73mm less than box outside dimension, which seems - reasonably consistent with my estimate of a 2mm wall thickness, about 1mm - for the lid lip, and some mold tolerances. So, let's use the box lid lip - inside dimensions as a proxy for the box base inside dimensions until proven - otherwise. - - So we need to peel 5 mils off to account for the box radius. The flange - itself is 40 mils. And I'm nervous about the guesstimates so I'll add - another 5 mils of margin. So we need to take 50 mils off the SMA end of - the PCB. - - As a sanity check, on TeleDongle the closes screw hole is 78 mils from the - SMA edge of the PCB, which is 50 mils less than a maximum-size PCB would - have. If anything, the TeleDongle SMA ends up inside the wall a bit more - that necessary, such that tightening the SMA nut deflects the wall inward. - So, 50 mils might indeed be a good choice for TeleBT. We'll give it a try! - -2011.06.07 -- as I start to work on rotating the design, noting the changes between the - max 1551 board outline and what I used for v0.1: - - outline layer: - - - Line[278543 24606 291339 24606 1000 2000 "lock"] - - Line[291339 24606 291339 129921 1000 2000 "lock"] - - Line[287402 133854 24606 133854 1000 2000 "lock"] - - Arc[287402 129921 3937 3937 1000 2000 90 90 "lock"] - + Line[278543 24606 286338 24606 1000 2000 "lock"] - + Line[286338 133854 24606 133854 1000 2000 "lock"] - + Line[286338 24606 286338 133854 1000 2000 "lock"] - - similar changes on the top layer: - - - Line[287402 133854 24606 133854 100 2000 "clearline,lock"] - - Line[24606 133854 24606 121063 100 2000 "clearline,lock"] - - Line[12795 109252 0 109252 100 2000 "clearline,lock"] - - Line[3927 0 266732 0 100 2000 "clearline,lock"] - - Line[291339 24606 291339 129921 100 2000 "clearline,lock"] - - Line[278543 24606 291339 24606 100 2000 "clearline,lock"] - - Line[266732 0 266732 12795 100 2000 "clearline,lock"] - - Line[0 109252 0 3937 100 2000 "clearline,lock"] - - Arc[3937 3937 3937 3937 100 2000 270 90 "clearline,lock"] - - Arc[278543 12795 11811 11811 100 2000 0 90 "clearline,lock"] - - Arc[287402 129921 3937 3937 100 2000 90 90 "clearline,lock"] - - Arc[12795 121063 11811 11811 100 2000 180 90 "clearline,lock"] - + Line[286338 24606 286338 133854 600 2000 "clearline,lock"] - + Line[286338 133854 24606 133854 600 2000 "clearline,lock"] - + Line[24606 133854 24606 121063 600 2000 "clearline,lock"] - + Line[12795 109252 0 109252 600 2000 "clearline,lock"] - + Line[3927 0 266732 0 600 2000 "clearline,lock"] - + Line[278543 24606 286338 24606 600 2000 "clearline,lock"] - + Line[266732 0 266732 12795 600 2000 "clearline,lock"] - + Line[0 109252 0 3937 600 2000 "clearline,lock"] - + Arc[3937 3937 3937 3937 600 2000 270 90 "clearline,lock"] - + Arc[278543 12795 11811 11811 600 2000 0 90 "clearline,lock"] - + Arc[12795 121063 11811 11811 600 2000 180 90 "clearline,lock"] - -2013.01.25 -- reviewing design with an eye towards moving to production - - - we have the ability to sample v_lipo, but is it useful? - -- need to move design to current preferred parts list -- verify button fits cleanly through box wall -- artwork is solid .. did a lot for v0.3 - -2013.04.08 -- problems in v1.0 build fixed for v1.1 - + companion and debug connectors should be rotated so cable dresses - towards center of board like TD - + update D1 footprint to clearly indicate cathode end so we don't - mess that up again - + we're not loading the flash part, so just remove it - -2016.03.20 -- to build a TeleBT with BTle: - + swap out Rayson module for DK BM70BLES1FC2-0002AA-ND - ? swap out CPU for STM32F042, since it has in-built USB bootloader -- 2.30.2
