Advanced PCI Express Mini Card (mPCIe) Carrier Board (1x4) for 104-Express


  • Converts one PCIe x1 lane from stack into four PCI Express Mini Card sockets
  • Supports half- or full-size mPCIe cards, for use in a Type 1 or Type 2 PCIe/104 stack
  • All four sockets support USB, SMBUS, micro-SIM, as well as PCI Express signals
  • mSATA devices supported on two sockets (Type 2)
  • Powered from the PCIe/104 stack 5V rail, no 12V needed
  • 2mm standoffs integrated into design for easy installation, hardware included
  • RoHS and industrial temp (-40°C to 85°C) standard



  • Top stacking (-TOP) (designed for use on top of stack)
  • One Bank connector (-1B)


The 104e-mPCIe-4A is a Type 1 or Type 2 PCIe/104 carrier board designed to support up to four PCI Express mini cards, in either half or full lengths, while only consuming one x1 PCIe lane from the bus. In addition the board supports up to two mSATA devices (via dip-switch selection -Type 2 only), and all four sockets support USB, SMBus, and wireless mPCIe devices — including micro-SIM sockets, per socket, for cellular (WAN) use.

The advanced carrier board is a great way to use ACCES’ full industrial line of mPCIe products. These include isolated DAQ, serial, analog, digital I/O (TTL, LVTTL, relay, FET) and quadrature cards.

Having four peripheral device sockets on one PCIe/104 stack-height card truly multiplies the flexibility of your embedded designs without compromising size or ruggedness.
