Gerber Files

This is a centralised index of Gerber Files which have been used for BATC and BATC Members' projects.

No responsibility is accepted for any errors, but they are listed here to promote home construction and experimentation.

Files should be uploaded as .zip files, and should also be referenced from another Wiki page describing the project.

G0MJW's Ryde board

This is like a plug in board for the PI4 that provides the 5V PSU, a cooling option and Ryde IO interface. The information is all below. There are two PSU options, only one is required. All fairly simple. These Gerbers are set up for JLC PCB. In theory all you need to do is upload the zip file with the gerbers and select quantity, solder mask colour and postage options. The BOM is an HTML file in the ibom zip.

G0MJW's PD4 board

TBC (after CAT22)

This is a PCB to implement a Portsdown 4 with 25 pid connector for interfacing to test equipment.

BOM File:ibom25way.zip

Sorry there is no parts list for Farnell, etc because the parts they supply just change too often. The resistors and capacitors are mostly standard 0805 SMD, there are two electrolytics, non critical and you may want to fit a larger 2512 SMD resistor in the fan supply to slow it down if too loud. The headers Molex KK254 or equivalent, with a PI GPIO header socket on the bottom of the board. There are two PSU options, only one needed with the small MCP1584 DC-DC module, like used in the Minitiouner, probably the easiest to obtain, if you fit this there is no need for the voltage programming resistors R1, R2 and R3 needed with the alternative Murata module - see the schematic. Needless to say, the MCP1584 module pot has to be set for 5V before connecting the PI. I got my DB25 from AliExpress, but they are available from major suppliers.

G0MJW's HF3 relay board

Here's Mike's design for a SPDT relay PCB. The relay is General Purpose Relay, HF3 Series, High Frequency, Non Latching, SPDT, 12 VDC, 2 A. Part number is dependant on the voltage in use in circuit. A surface mount diode e.g 1N4148 type, Molex KK connector and 3 SMA to PCB unions complete the build.

LNB bias tee and reference injection PCB

PCB Gerbers for the LNB Bias T and reference injection by Mike G0MJW in CQ-TV263 – or see BATC forum for more details: https://forum.batc.org.uk/viewtopic.php?f=15&t=3122&p=17416#p17343

M0RNW's G8TA Rx/Tx Changeover Controller Board

This is v1 designed for a latching relay of up to 6 into 1 ports using an Arduino Nano. Hopefully it features in CQ-TV-279. PCB is intended for rail mounting in a 3U cabinet.

Three SN754410NE H bridge driver ICs are used. The DC-DC boost converters are XL4005 type boards off EBay. U2 can be omitted - it's for an 18V supply to an LNB. Other components - see schematic.
