+#/* BOM for O+C (rev 2c) */
+
+- if your board is is labelled rev.2c (on top of the board, underneath the 'ornament and crime' label), that's rev 2c. previous versions differ only slightly.
+
+- the footprint for passives is **0805 throughout**, except the four 10n caps (0603) in vicinity of the teensy. using 0603 everywhere will work just as fine, of course.
+
+- there's four 3-pin pads for 2k trimpots (output calibration): **we recommend omitting the trimpots**, and doing the calibration entirely in software. use four **jumper wires** instead and, ideally, **0.1% resistors** for the output stage (the "wiki" has more details): it's cheaper and makes calibration easier (and no less accurate).

+| 100k | 8x | e.g. mouser # 660-RK73H2ATTD1003F| 1% (or simply get 12 x 0.1%) |
+
+- (‡) **if** building **with** trimpots, use 24k (1%) rather than 24k9.
+
+
+### trimpots (throughhole):

+
+- (†) something fancier (= more suitable, $$) than TL072 should be used for the DAC output stage; using TL072 will be ok, but ideally, you want something with (very) **low offset/noise/drift**. for example: OPA2172, OPA2277

+- (†)  rotary encoder w/ switch: for instance: mouser # 652-PEC11R-4215F-S24 (15 mm, 'D' shaft); 652-PEC11R-4215K-S24 (15 mm shaft, knurled); 652-PEC11R-4220F-S24 (20 mm, 'D'), 652-PEC11R-4220K-S24 (20 mm, knurled), etc).
+- (††) best to **use "machined pin" ones** (also called "round" or "precision"): the pcb holes are small.
+- (†††) much cheaper is [sos](http://www.soselectronic.com/?str=371&artnum=102165&name=mec-5gth935).

+| teensy 3.2 / 3.1| 1x | **cut the V_usb/power trace!** | [oshpark](http://store.oshpark.com/products/teensy-3-1) / mouser # 485-2756 |
+| OLED | 1x | SH1106 or SSD1306 / 1.3" / 128x64 | see note (†) | 
+
+- (†) you can find these 1.3" displays on ebay or aliexpress for < 10$. as long as the description claims that they are `SH1106` or `SSD1306` and the pinout is: `GND - VCC - D0 - D1 - RST - DC - CS`, they should work (or `GND - VCC - CLK - MOSI - RES - DC - CS`, which is the same). **make sure you get the right size**: 1.3" (not 0.96")! 
+- alternatively, the hardware/gerbers folder has **.brd/.sch** files for a/the OLED carrier board. in that case, you'd need to get the bare OLED. [for example here](http://www.buydisplay.com/default/serial-spi-1-3-inch-128x64-oled-display-module-ssd1306-white-on-black) (though there's cheaper options for getting bare OLEDs).
