- atusb.pro, atusb.cmp: updated for ATmega32U2-based design
- usb.sch: rearranged LED, nRST_RF, and SLP_TR, to make layout easier
- atusb.brd: redid layout for the ATmega32U2-based design
- atusb.pro (LibName5): changed from c8051f326 to atmega8u2
- atrf.sch: export CLKM and added filter for 8 MHz clock
- atusb.sch: connect CLK between RF and USB side
- usb.sch: changed design frim C8051F326 to ATmega32U2 (needs cleanup)
Settings according to
http://www.nxp.com/documents/mounting_and_soldering/AN10365.pdf
- atben.pro, atben.brd, atusb.pro, atusb.brd: set solder mask clearance
to 50 um (copper-defined pads)
- atben.pro, atben.brd, atusb.pro, atusb.brd: set solder paste clearance
to 25 um
- atrf.sch: replaced the AT86RF230 with the AT86RF231
- atusb.sch, usb.sch, atrf.sch: removed TST signal
- atrf.sch: grounded former TST pin
- atusb.brd: updated for TST removal
- atusb.brd: increased space between SLP_TR and nRST_RF vias
- atusb.brd: connect U2 pin 6 to ground pad
- atusb.sch, usb.sch, atrf.sch, atusb.brd: changed version to 20110104
- atusb.pro: reduced edge and drawing line width from 15 mil to 5 mil
- atusb.brd: added ground zones on bottom layer
- atusb.brd: moved IRQ_RF and VDD traces for better ground area coverage
- atusb/atusb.pro: instead of modules/meander, use experimental ants/meander
- atusb/atusb.pro: typo - it's modules/usb_a_plug_smt, not
modules/usb_a_plug
- atusb/atusb.cmp (ANT1): change antenna from "meander" to "MEANDER-110"
(10% enlarged)
- atusb/atusb.cmp (CON1): change from "miniUSB_B" USB receptacle to
"USB-A-PLUG-SMT" plug
- atusb/atusb.cmp (VR1, VR2, VR3): update value from schematics
We know from CNTR that the capacitance of the 0603 TVS (EPCOS CT0603M4G,
200 pF) is too large and can disturb the USB signal. The 0402 TVS
(Panasonic EZJ-P0V080GA, 100 pF) works much better.
Since we have lots of 0402 components already, just change the remaining
0603 to 0402, too.
- usb.sch (VR1, VR2, VR3): change from 0603 to 0402 and from 5V5 to 5V6
- usb.sch (C1, C2, R1): change from 0603 to 0402
- atrf.sch (R3): set footprint to 0402
- atusb.pro: replaced modules/mini-usb with modules/usb_a_plug
- atusb.pro: removed extension from components/balun-smt6.lib
- atusb.cmp: update footprints for above changes
- atusb.cmp: change 0402 to 0402-M and 0603 to 0603-M, for easier
soldering
This way, we can plug the device into a USB port, like a USB stick.
We use a real plug (instead of shaping the PCB in the form of a plug)
for better mechanical stability.
- atusb.pro: change from components/mini_usb_b to components/usb_a_plug
- usb.sch (CON1): replace MINI_USB_B with USB_A_PLUG
- atrf/: rename to atusb/
- atrf/wpan-atrf.pro, atrf/wpan-atrf.sch, atrf/wpan-atrf.brd,
atrf/wpan-atrf.cmp: rename to atusb.*
- atrf/Makefile: change ben-wpan to atusb
- atrf/atusb.pro (LastNetListRead): update for name change
- tools/Makefile.common (CFLAGS): change fw/ include location from atrf/
to atusb/
