Maybe it's an idea that someone actually can make a summary, make a new topic and make that as a sticky?
I have the idea that a few people here know exactly what's going on and what/where to find everything.
But to me it's also a huge maze to go through.
I can honestly say that I've just finished reading all 195 pages and will rescan to pick up the parts that I've tagged that are of special interest to me.
Isn't it possible to modify the "m" version code to support the configuration utilising U4.
I will draw an updated diagram and post if it anyone wants it. I can also take a picture of the 2 different but similar PCB's and post those if people are interested.
I am new to the source repository and find this thread very useful but still not sure which repository version to download as a starting point for converting a TC1 with ATMEGA 324. I downloaded ComponentTest 1.33m and it does not have an archive folder, so I must have the wrong file.

jakeisprobably started working on a FAQ/how-to a while ago but I don't know the current status.
At this moment people need to read through a whole bunch of pages to discover that the firmware can even be changed.
I am trying to work out what is available as a replacement part to improve the 5v regulation on the TC1 from the 78L05 SOT-89 they use.
Would anyone with knowledge of the tolerance requirements cast your eyes over the attached specs of a couple of pin compatible SOT-89 LDO's with better line and load regulation I have found?
Below are links to the data sheets, could not attach them (not for lack of trying, they were over the size limit allowed):
Element14, LD2981 http://www.farnell.com/datasheets/2310115.pdf?_ga=2.139301427.1894826597.1530201477-1167880404.1500891526
Mouser/Digikey AP7381 https://au.mouser.com/datasheet/2/115/AP7381-1220674.pdf
If these look suitable I will order the one from Element14 first and see how they perform.
You don't need ldo you need precision regulators I guess.

read again, the folowing is an abstract of the Microchip MCP1702 datasheet:
"The MCP1702 is capable of delivering 250 mA with
only 625 mV (typical) of input to output voltage
differential (VOUT = 2.8V). The output voltage tolerance
of the MCP1702 is typically ±0.4% at +25°C and ±3%
maximum over the operating junction temperature
range of -40°C to +125°C. Line regulation is ±0.1%
typical at +25°C".
Do you really use electronic circuits at home and operate your tester over this range ?
EDIT:
reading further, @25°C, min and max Output Voltage tolerance remains within +-2% !

Actually it should be simple to extract the component type and its pinout from the serial output. Another way would be to enable the remote commands to retrieve type and pinout directly.
