I think I will try to find a connector that can fit on either the 25 or 35 pin footprint to make life easier. | I think I will try to find a connector that can fit on either the 25 or 35 pin footprint to make life easier. | ||

| + | Of, here are a few of the things done: | ||
| + | |||
| + | *Board Shrinked | ||
| + | *Mounting Holes Added | ||
| + | *Battery Voltage Analog Signal | ||
| + | *FET Driver Schematic Updated | ||
| + | *Switching Power supply | ||
| + | |||
| + | Here is a low quality image of the layout. | ||

| + | |||
| + | Soon: 25 Pin connector and aftermarket connector. | ||
| + | |||
| + | I have found good connectors from Phoenix Connectors that I like. I will be putting the footprint for a 32pin connector on the PCB sometime. I decided to use a 32pin connector because that suits my PCB layout the best. I will try to make the pinout as close as possible to the 25/34 pin layout to make the change easier. | ||
| + | |||
| + | I shrank the board quite a bit. It is now 123mmx100mm. This will decrease the board cost and will make it easier to fit into aftermarket enclosures. I have found some really good enclosures for PCB up to 135mmx100mm. | ||
| + | |||
| + | A change to surface mount protection diodes reduces the amount of through hole components that I need to solder on. | ||
| + | |||
| + | A switching power supply is made because it will increase efficiency and lower the heat generated. I also dont need an intermediate voltage for the FET drives, meaning that I only need 12V and 3.3V rails. | ||
| + | |||
| + | After the connectors are sorted then the PCB should be finished! | ||
