 The only difference between V0.8 and V0.9 boards is the silkscreen. There were a few changes to the text on the board but the schematic and layout is identical.

 ## Instructions for use
 You can find the instruction for use as added to the shipment of the fully populated boards [here](https://github.com/bbqkees/Nefit-Buderus-EMS-bus-Arduino-Domoticz/blob/master/PCB-files/V0.9/EMS%20bus%20interface%20board%20manual%20V0.9.pdf).
 
-## Components
-I have almost all components in a nice [Reichelt shopping list](https://www.reichelt.de/my/1489718).
-### Instructions before ordering based on the Reichelt shopping list:
-- Double check the schematic and the component list below when you load the shopping cart.<br>
-- Sometimes components sell out or have a long delivery time. You need to replace those components yourself with alternatives that are equal. Usually Reichelt has enough alternatives. Its possible to fit a 0603 or 1206 on the 0805 footprint. For passives (resistors and capacitors) if equal components are not availble, you can try the next lower or higher value. For the capacitors on the EMS bus side you want ones that can handle 20V or higher.<BR>
-- At this time the 10uF 0805 capacitor is not available at Reichelt *at all*. You could f.i. fit a slightly larger size on the board. <BR> If you buy the bare PCB from me I'll add one to the shipment.<br>
-- For the full board you need 8 header pins. In the shopping list there is a single row of 40 pins so if that one sells out just get a strip with at least 10 pins as usually you'll break off a few which you cannot use anymore.<BR>  
-- What Reichelt does not have are the polyfuses. I use the Multicomp MC36207. I got them from [Sinuss.nl](https://sinuss.nl/componenten/passieve-componenten/thermistors/pptc-resettable-fuse/1861187-mc36207-fuse-ptc-reset-30v-200ma-smd-multicomp) But you can also get these or similar from [Farnell/Element14](https://nl.farnell.com/multicomp/mc36207/fuse-ptc-reset-30v-200ma-smd/dp/1861187).<br>If you buy the bare PCB from me I'll add those two to the shipment.<br>
-  If you want to omit the polyfuses just solder a piece of wire across the footprint of F1 and F2 or solder a 0805 zero Ohm resistor.
-- The screw terminal (J1) is a 5.08mm 2-pin screw terminal I got from Ebay [(Like these)](https://www.ebay.nl/itm/40x-2Pin-Screw-Terminal-Block-Connector-5-08mm-Pitch-Panel-PCB-Mount-Repalce-Kit/292743000390). A black version is also in the Reichelt shopping list.
-- Do not replace the jack terminal with another type, as its footprint is very specific and others will either not fit or they have the wrong pinout.<br>
-- L1 and L2 are for SMD inductors. If you want to use axial through-hole inductors instead you need to use L3 and L4. do not use both L1/L2 and L3/L4.
