Core Modul: Resistor R1 ?? 100kohm /100 Ohm

[Guest stefan]

I am not sure about the resistor r1 on the Core Modul.

In the Reichelt-Orderlist is it listed as 100k.

But in the Circuit and Schematic it is only named as 100 (?)  I have now soldered an 100k resistor but I can only measure 2,5V on Pin MCLR.

What is the right value ?

Hi

I think it was 100ohms (not Kohms)

Im at work at the moment so I can't check but if no-one else has replied I will let you know when I get home.

LO

???

Sorry forgot to check  >:(

Wrote myself a note to check tonite!

I soldered a 100Kohm, like in the partlist

and it works fine. I will check my MCLR Value?!

Sorry, this was an error in the part list (fortunately the schematic, the PCB and the Reichelt ordernumber was correct) - it should be a 100 Ohm resistor. Btw.: the resistor just only opens the possibility to reset the PIC without a power-off by applying Vss to MRST# for a short moment. It's for my personal use ;-) --- instead of buying a new resistor, you can just bypass it (take a bridge and clamp the MRST# pin directly to +5V)

...MCLR is about 5V with R1=100kohm....

Ok I have now soldered a 100 Ohm Resistor and everything is alright. MCLR=5V ;D

@xt-rem

are you sure you have used 100 KOhm
