I just took some of my personal experiences, created a simple-to-understand architecture, used off-the-shelf components (no GAL or CPLD) with nothing that would require sophisticated tools to test or implement. Most importantly it's all open source so you can build it yourself, and for ...
B version of the board the labels were more legible is the socket was spaced off the board a mm or so with some diode leads under the socket. The newer rev. B2 board has labels between the pins which makes this unnecessary. For larger and multi-pin components, such as the chip socket...
(These pictures show the original Zumo Shield, but the assembly process also applies to newer ones including the latest v1.3 version.) Through-hole parts Solder the included through-hole components to the shield: buzzer charging connector (1×2-pin female header) power switch (original and v...
PCA9685_ACTUAL_CLOCK_FREQUENCY25000000LChange it, if your PCA9685 has another than the default 25 MHz internal clock. See chapter 2 and 5 of the PCA9685 Datasheet "25 MHz typical internal oscillator requires no external components". This value is taken for all attached PCA9685 expanders!
They PCB’s are cheap to get made but the SM components may put some people off. I have been programming it in Arduino as libraries are readily available for the peripheral hardware. When fully populated you have: Ethernet (Wiz820) micro SD card battery-backed RTC 2 x logic level serial...
