Intel Atom E3845 Bay Trail Qseven module, 2 GB DDR3L, 4 GB eMMC (P/N 015100)
The congatec conga-QA3/E3845-2G eMMC4 (P/N 015100) is a Qseven 2.0 computer-on-module with the quad-core Intel Atom E3845 Bay Trail SoC, 2 GB dual-channel DDR3L and 4 GB onboard eMMC. It was widely designed into industrial automation, medical, kiosk, transportation and digital-signage systems from 2014 onwards. congatec now marks the conga-QA3 family as EOL (end of life), so remaining units come only from residual or broker stock and supply is constrained. Cerametronics helps buyers locate traceable remaining stock for ongoing production.

FAQ
What does the part number conga-QA3/E3845-2G eMMC4 encode?
QA3 is congatec's Qseven module family for Intel Bay Trail; E3845 is the Atom E3845 quad-core SoC; 2G = 2 GB onboard DDR3L; eMMC4 = 4 GB onboard eMMC (congatec P/N 015100). Related variants include /E3845-2G without eMMC (P/N 015109), /E3845-4G eMMC8 (P/N 018105), /E3845-8G eMMC16 (P/N 015131) and the industrial-temperature /i-E3845-2G eMMC4 (P/N 015120).
Is the module still available and what can replace it?
congatec's product page lists the conga-QA3 as EOL and names no direct successor. For redesigns, congatec's current Qseven offerings include the Intel-based conga-QA5 and conga-QA7 and the NXP-based conga-QMX8-Plus; a carrier re-spin and BSP change should be expected. The original evaluation carrier is the conga-QEVAL/Qseven 2.0 x86.
