A PCRE internal error occured. This might be caused by a faulty plugin

====== RES-SD module ====== This is a very simple board performing three functions: * SD card socket * Reset button * Indicator LEDs ===== Schematic ===== Connector J16E (SMT male header) carries 3v3 power and data signals for the SD card, along with the Reset and "LED" signals. The Reset button has a damping capacitor. The LEDs are connected through limiting resistors. The cathode pins are closest to the edge of the board. ---- ===== BOM v1.0 ===== ^Type ^Qty ^Value ^Package ^Parts^Mouser^Reichelt^Conrad^Other^Notes^ ^Resistors^^^^^^^^^^ | |4 |~1k 5% |THT |R1-4 | | | | |depends on LEDs | ^Capacitors^^^^^^^^^^ | |1 |100n |1206 or THT |C1 | | | | | | ^LEDs^^^^^^^^^^ | |4 |Green |2*3*4 | | | | |eBay | | | |4 |Orange |2*3*4 | | | | |eBay | | | |4 |Red |2*3*4 | | | | |eBay | | | |4 |Blue |2*3*4 | | | | |eBay | | ^Switch^^^^^^^^^^ | |1 |tact low profile | |MJTP1117 | |700310 – 62 | | | | ^Headers^^^^^^^^^^ | |1 |2*8 |**SMT**male | | | | | |could use a longer strip | ^Sockets^^^^^^^^^^ | |1 |SD | |SD-RSMT-2-MQ | | | | | | ^Hardware^^^^^^^^^^ | |2 |M3 Spacer |5mm(?) | | | | | | | ===== Versions ===== v1.0: first release. **Important!** v1.0 boards have an error with the Reset switch. All boards should have one trace cut (shown in white), but it is required to bridge a pin with the adjacent mounting pin (as circled in red) {{::wcore:res-sd:resfix.png?nolink&200|}} ===== Assembly ===== The following build order is suggested: ---- ==== License ==== Currently the design is (c) 2017 antilog devices with all rights reserved; all documentation is CC BY-NC-SA 3.0.
