Re: Check my first design?

Thanks for all the help, everyone. I implemented *most* of the suggestions, and I just ordered parts and boards, so I'll give it a go soon. One pressing question that I have from this is concerning the "45-degree rule". Is that still a hard-and-fast rule these days? Also, on a related note, that is ...

It seems that the price of circuithub and macrpfab are not competitive.I ordered some PCB from EzPCB.For 5pcs 1.5"x1.5" pcb,just USD40 with free shipping.The quality is very good and they can be free assemble 1pc board for me. You can order the same size from OSH Park for half that. So what's assem...

Mike,
Thank you so much for the detailed response. This was the type of feedback I was hoping to receive. It will take a little while for me to digest and implement your suggestions, but I'll post a revised design ASAP!

I've attached PDFs, and also modified Eagle files, based on some suggestions I've received. One question I have in particular, is concerning the "Stop Mask" errors when I run the Sparkfun DRU (which I've included in the Eagle Files zip). Yes, I know that double-clicking will show me where the error ...

Yep, I ran it through both Sparkfun and OSH Park DRUs.

All, Thanks a lot for the previous notes. I've tried attached a redesign with a few changes. 1. I've tried to hold to a 45-degree trace angle as well as I can. On the fine pitch parts, that's not always possible. 2. I've added "load sharing" capability to the charger circuit. When the USB is attache...

It's my understanding that I can program the Arduino bootloader using SPI and another Arduino.

Parts should be on a 0.1" grid. It looks like most of your parts are on a 0.05" grid, but some of the parts aren't on that grid either. Thanks for taking a look, davep. I guess I wasn't too concerned about having my parts or schematic aligned to a grid, so long as they passed the DRC. Is that a req...

Schematic: Pull up resistor on RESET is not connect to positive. Hold alt and drag it over to attach it to the net. Well, crap. I should've seen that one. Thank you! The tiny lettering prolly won't be printed as it's too small for most houses. So what's a rule of thumb for typical screen print lett...

I just finished my first PCB design. I basically just took the designs from a couple different boards and put them together on one board. It's designed to be like the Moteino with an accelerometer and LiPo charger on board. I'd appreciate any pointers on what I've done wrong! In some cases, I opted ...

It seems that your posts are on the verge of being spam. No need to post in every forum. I don't think that's the case at all. I posted this question here and on Element14, thinking that those were two places where "makers" go. I posted a comment regarding Macrofab to both forums about a week ago w...

I recently found out about CircuitHub and Macrofab. Both companies seem to be great options for hobbyists. I submitted a design for a small Arduino-type board, about 1.5"x1.5" with 27 components on two sides. Macrofab quotes $31 for a single board, $251 for 10, and $1,847 for 100. CircuitHub quotes ...

I thought this was useful information, so I'd like to post it on this forum, even though it's rather old. I'm currently working on my very first PCB project, and I've gone to a lot of the sites for quotes. I have a relatively simple board, with an ATMega, and accelerometers, and a LiPo charger, with...

I know this post is a bit old, but I wanted to post on my status. I ran into the exact same problem. After reading this forum, I had a similar problem. I was using an 3.3V FTDI adapter from LowPowerLab that has worked interchangeably with a similar Sparkfun adapter on other projects. However, in thi...
