## Description

Your PCB design pal on the iOS platform!

You can use this PCB Toolkit for iOS to calculate:

- Maximum conductor length / bandwidth (Hammerstad/Jensen & IPC)
- Conductor Impedance (also differential precise calculation by Kirschning/Jansen & IPC calculation)
- Via properties
- Via θ (Thermal resistance), and for a via array (IPC)
- Low Pass Π-filter
- Fusing current (Preece, Brooks & Onderdonk)
- Maximum current or width for a trace (IPC-2521 and IPC-2221)
- Electrical clearance (IPC2221B)
- Pull Up calculator I2C

And now also:

- LED Resistor Calculator
- Mounting Hole Info
- Nearest E-Series Resistor Calculator (Solo/Serie/Parallel)
- Resistor Tolerance / Alpha Viewer
- Via Stitching Calculator
- Cload Calculator (XTAL)

And also links to standard house stackups of JLCPCB, PCBWAY and Aisler are included. 

I will add more calculations with updates. (One time buy, so you will get these updates without additional charge later) I am also open to feature requests.

The app supports light mode, dark mode, portrait & landscape mode and zoomed-in display.
