+# M2 to ethernet board design on kicad 8
+
+This repository holds the hardware for M2 to ethernet board which has a intel I225 .
+
+This board contains :
+ * a I225 : KTI225IT S LNNL from intel 
+	-advance feature : Time Sensitive Networking (TSN) –
+ * an 8-pin connector to manage an Ethernet network (need specific cable adapter 
+														to connect Ethernet network)
+ * a PPS output on UFL connector 														
+
+Release 1 : not working
+Release 1 : fixed bugs
+	* fix signal inversion: PCIE_TX_N with PCIE_TX_P
+	* fix Intel reference I225 with advance feature to to handle TSN
+	* remove from design solder paste from connectors
+	* add solder paste on ethernet transformer pads
+	* remove gnd plane under ethernet transformer
+
+Release 2 : add ons	
+	* PCIE SM bus is now connected I225 (normally not necessary)
+	* The flash can be programmed via an external SPI programmer. 
+		- 4 resistors need to be removed to operate this programming
+		- SPI bus connection and supply are on 1mm test point
+
+Release 2 published on 28.11.2024
+what remains to be done :
+* complete fonctionnel schematic rewiew
+* check bom (possibly reduce bom by grouping components)
+* generate fab files
+
