2 Module Hardware Details
The BR-LE5.0-S1A footprint is backwards compatible to the BR-LE4.0-S2A footprint with the following exceptions:
• Power must be connected to the new VDDH pin C4. This is a required change that must be done. If a
single layer board is being used a 7 mil trace can be run in between the other circular pads on the bottom of the
module to connect VDD to VDDH when using normal voltage mode.
• The USB pins have been relocated from pins 15-18 to pins A4, A5, B5 and C5. Pins 15-18 are now PIOs.
• The programming/debugging pins have been relocated from pins 28 and 29 to pins F3 and F4.
