03:54 PM osmo-clock-gen Bug #3857: Use SAMD XOSC / PLL / GCLK to allow lower reference frequencies
PA14 is XIN, and is already routed to the GPIO expansion header (see #3858). As discussed with laforge, we simply don...

07:56 PM OsmocomBB Feature #4030: design breakout board for GTM900-B
GTM900 exposes no LED at all, so the breakout only will get a power-on LED.
Should the modem reside _on_ the break...

07:45 PM osmo-clock-gen Feature #3856 (Resolved): Use SAMD21 instead of SAMD11
design of v2 done
07:43 PM osmo-clock-gen Bug #3857 (Resolved): Use SAMD XOSC / PLL / GCLK to allow lower reference frequencies
XA input of Si5351C is now connected to Cortex' PA10, which also can be GCLK_IO4. They are connected via a series res...
06:58 PM osmo-clock-gen Feature #3905 (Resolved): allow user to supply different output voltage
after discussion on the RFC mail from laforge, a single R2R / single supply / unity gain stable opamp w/ BJT follower...
05:49 PM osmo-clock-gen Feature #3858 (Resolved): Make more GPIOs avaliable for future use
allocated PA11, PA14 and PA15 as additional GPIOs on a pinheader (together with VDD and GND).
