About the EmoeNAP PCB

EmoeNAP is an open source PCB design by Floyd-Fish, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 75 × 36 mm, with 156 components from 47 distinct parts.

Other key parts include the OPA1612, PS-12E05, OPA1679, LT1364 and TP4057. By type, the board carries 73 capacitors, 55 resistors, 12 ICs and 8 connectors.

It belongs with the audio and test & measurement designs in this gallery.

From the project

An ultra-low noise amplifier to measure low-noise LDO/OPA's wide band output noise, and many other interesting measurements. Referred to AN-159.

- NoiseAMP_BAT > The battery pack for Noise Amplifier. Two 14500 Type 3.7V Li-ion Battery are used to provide ultralow power rail noise and high output current for NoiseAMP to work.

- NoiseAMPV2.3(Aborted**) > The main PCB of the initial version of NoiseAMP, the current revision named EmoeNAP.

- EmoeNAP > The current main PCB of NoiseAMP, called EmoeNAP, too.

To build a single cell EmoeNAP，just use EmoeNAP is enough. To build a 2-cell EmoeNAP, maybe you could have a look at NoiseAMP_BAT.
