Here I have my 3.3v switching regulator (TPS62056DGS) represented by an op amp with a reference voltage at 1.3v. Power switches usually come in two types. IвЂ™ll refine.Д«y Oklahoma Robotics | | From the TeamPrototype Circuit for Toggling Here is the toggling circuit I am working on as represented in the iCircuit iOS simulator. board with a ground pour that uses the momentary switch to jump over a track. The standby current at 6v input level is now only 1uA! My latest estimate of the quiescent current of the toggling/control system is ~50uA. After click the Run button, The real time check box will let you see. Beau Schwabe, IC layout engineer and member of our local Ohm Space, revised a circuit he.Д«y Oklahoma Robotics | | From the TeamToday I populated another regulator PCB, leaving out the components that wonвЂ™t be in the final design. It also depicts a momentary pushbutton switch as a holdover from the previous revision. I tried to redo it with decoupling caps, but there are so few examples out there of anyone using any sort of decoupling on reset and I don't think I fully understand its purpose for being there.By Oklahoma Robotics | | From the TeamThis diptrace schematic is a minimal circuit using theВ TPS62056DGS voltage regulator. But that clearly isn't best practices, as this reset circuit has been mentioned by multiple redditors. There is no decoupling cap, no diode, nothing. The downloads from OSHpark includes the source files for diptrace for anyone that wants to play around with it, along with. PSMN3R0-30YLDX is a popular cheap option, the SIR800DP is better but costs more. I started off with a reset circuit that I know works, because I copied off of these little boards here, that have been using for months without issue: But they use a reset circuit that is literally just a pullup and a momentary switch to ground to reset the chip when pushed. U1 : SOIC-8 for the Attiny85, the 13, 25 & 45 also fit on them U2 : LFPAK56 MOSFET (aka, FET). Should I put my preface in the schematic itself as a text block or just put it in the body of the reddit post? messier looking for lack of a better word. I had the pullups on their respective sides at one point but it made the circuit. 30 GPIO pins (26 exposed) Can support USB Host or Device mode. Runs at 48MHz, but can be overclocked to 133MHz. It has some impressive specifications: Dual-core 32-bit ARM Cortex-M0+. I thought it looked cleaner and easier to read with the pullups beside each other and sharing a 5v bus but that does result in a crossed connection. The Raspberry Pi Pico is based around the FoundationвЂ™s new chip, the RP2040 microcontroller. The OLED will be on a nearby but separate pcb along with the rotary encoder (all on sheet 3). I put them on the OLED side of the circuit but I can put them closer to the MCU if that is better practice. Added pullups on the i2c lines for the OLED header. I am not interested in auto reset by the programmer, the serial-ttl-usb adapter I will be using in the rare event I need to program in-circuit doesn't utilize auto-reset. There are so many different examples online and I feel at this point I've tried 99% of them. Hey Everyone whats up.So heres one of the previous projects I made a few weeks ago.Voronoi Diagram-Based PCB Lamp is an RGB Lamp made entirely from PCBs, I used four rectangular PCBs with two square PCBs to make the body of the LAMP.RGB Color in this Lamp can be changed by pressing the button on top of it, this button is connected with the. I'm still not confident it is correct but at this point I think I might need someone to draw me an example. It's not as readable in my mind but I definitely see the point regarding pin confusion/readability and at the end of the day, the crossing is fairly minimal for the most part. Cleaned up connector order at the expense of not crossing connections.

Between this sub and r/pcb I have received an absolutely incredible education in basic design practices for laying out a schematic. I would just like to start by thanking everyone here for all the help.
