Issues With Board Ver. 7 #1

Open nhz2 opened 4 years ago

nhz2 commented 4 years ago

Errors

  1. Silkscreen error: SCLK CLK should be flipped on probe points for chip.
  2. Schematic error: R9(300K) should go from DETB to +5V not GND

Slight improvements

  1. Line up caps for easier drag soldering of ADCs.
  2. Move probe points away from chip, so easier to probe with ZIF socket.

I fixed these issues in the new version of the PCB and schematic on https://easyeda.com/nzimmerberg/amp-chip

The R9 resistor could also be desoldered and a new 300k ohm resistor be soldered between DETB aka pin 15 on the BNK chip and one of the 5V holes.
