Bottom

2 layer board of 2.45 x 1.55 inches (62.3 x 39.5 mm)
Uploaded: December 10th 2022
Shared: January 18th 2023
Total Price: $19.05

This is a redesign of Chameleon USB FX2 (cusbfx2). Board dimension and pin assignment are all the same as cusbfx2, but changing some parts and move all components to top layer.

You will need good sodering skill to complete this project.

Lots of 0402 package resistors and capacitors need to solder

Lots of TSSOP/TQFP/SSOP components need to solder

BOM

Part Package Value Mouser part no. Qty Note
C1,C2 0402 18pF 80-C0402C180K5R7867 2
C3,C4 1206 10uF 810-C3216X7R1H106160 2
C6-C21 0402 0.1uF 581-04025C104KAT4A 16

U2 TQFP100 EPM570T100C5N - 1
U3 TSSOP8 24LC128 579-24LC128-E/ST 1 Optional
U4 SOT-23-5 TLV75733P 595-TLV75733PDBVR 1
X1 Type-B Female Mini USB Connector 571-1734035-3 1 710-65100516121 or 490-UJ2-MBH-2-SMT should also work

MAX II chip (EPM570T100C5N) is not easy to find right now so basically find a working MAX II chip (make sure is a EPM570T100) first, then order PCB and others parts.
