About the Duke Fluke'EM Probe Public Version V5 PCB

Duke Fluke'EM Probe Public Version V5 is an open source RP2040/RP2350 PCB design by novintic, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 114 × 56.7 mm, with 75 components from 45 distinct parts.

Its main chip is the 2040 Pico, from the RP2040/RP2350 family. Other key parts include the JFE2140, LM361 and SN74LV1T34DBV. By type, the board carries 27 resistors, 18 capacitors, 6 ICs, 5 connectors, 4 transistors and 4 test points.

From the project

HW/SW solution for Fluke 9010 mainframe emulation

This add-on board for the FluCom Raspberry Pi HAT provides full probe functionality for the FlukeEmu/FluCom hardware/software Emulation of the Fluke 9010A Micro-System Troubleshooter.

Basically this makes the Fluke 9010A emulation feature- complete.

As much of the original circuitry as possible was implemented using a Raspberry PICO microcontroller.

However, due to the original design of the probe, a significant amount of analog circuitry had to be reproduced in order to keep the system working with legacy probes.
