Re: Mini-Mod 2021!
Hopefully this is the final version of the MK2 Minimod.
Ian has now finalised the design with the added buffer stage.
I have added the features described above and I have also added a 78L09 regulator, diode and capacitors for those who wish to use an external power supply.
The components for this are numbered from 100 to distiguish them from Ian's design
For battery use, or if you do not want to use the regulator, simply omit the regulator and replace D101 with a link. The extra capacitors do no harm and can be fitted if you wish.
I have still kept the pcb size the same to allow it to be easily fitted in place of the Mk1 board for those who want to compare the versions.
I will leave it for a few days for any other comments / requests before ordering the pcbs.
