The 3040 is very small and compact and, as a result, there is negligible internal space for 'add ons' other than the socket provided for the M.2 wireless module.
The label on the 3040, as well as identifying it as a 3040, also says 'Reg Model:N10D'. I assume the N10D name is the 'Regulatory Model' which explicitly identifies the hardware that has undergone various EMC, recycling and other certification tests. The '3040' moniker is the marketing name which could change depending on what software is installed and the market it is being sold into.
It was launched in March 2017. My example was manufactured in October 2019.
The basic specs are:
Intel Atom x5 Z-8350 (Quad core)
2560 x 1600 32-bit colour (x2)
2 x Display Port
1 x USB2.0, 1 x USB3.0 (front)
2 x USB2.0 (rear)
Dimensions H x W x D (mm) 28 x 102 x 102
ThinLinux 1.0.4 (post RTS)
PCoIP enabled Wyse ThinOS
My 3040 came fitted with 16GB of flash.
Unusually for modern thin clients the 3040 runs off 5V. The coax plug is 4mm x 1.7mm.
In May 2021 I heard from April who had got hold of a 3040 but hers ran off 12V. Investigating this led me to the Dell community pages where, in August 2020, somebody posted the as yet unanswered comment:
"...our latest 3040 clients come with 12v supply and 12v stated on the underside but our older 3040 clients say 5v on the underside and 5v on the supply.
Both plugs fit in both clients so I would also like to know if they are interchangeable. Otherwise it is just an accident waiting to happen that someone plugs in the wrong adapter."
On a revisit to that page I see there have been several requests for an update including one in November 2021:
"Update would be nice.... One of my interns just killed a 5v model plugging it in to a 12v adapter....."...which I guess answers the question.
At least with DELL thin clients the required supply voltage is marked either by the power socket or on the product label. The pictured label is off my 3040.
Intel Cherry Trail x5 Z-8350 (1.44 GHz Quad Core).

Flash: The internal memory is either an 8GB or 16GB eMMC flash chip soldered to the motherboard. It is not replaceable.
RAM: There is 2GB of DDR3L RAM soldered to the motherboard. You are stuck with 2GB.
Wireless: There is a socket on the board to take a wireless module. This is a M.2 socket with a key ID of E. The 3040 datasheet gives the factory fit part as 'WLAN+BT Combo Module: Azurewave AW-CM389MA w/Marvell 8897chip, M.2 2230 (SDIO interface)'.
Note the 'SDIO interface' above. Whilst a M.2 E slot can support 2x PCIe x1, USB2.0, I2C, SDIO, UART and PCM interfaces, it appears that the slot on the 3040 only supports SDIO.
By far the majority of wireless cards use a PCIe interface for WiFi and USB for Bluetooth. None of these will work in the 3040 - as confirmed by Jonathan in January 2021.
From a quick check the AW-CM389MA appears to be difficult to source in the UK. (Options I have seen: £100 minimum order; 1,500 minimum quantity; $50 postage from USA for a $13 part.) In a brief search I wasn't able to locate an alternative to the AW-CM389A at a price less than I paid for the 3040. If you know of another cheap M.2-E SDIO wireless card please let me know.
In February 2021 I heard from Carl who had several 3040s with the factory fitted AW-CM389A. These were working fine and running Alpine Linux. So, though the cards may be hard to find, they are supported in the Linux kernel.
If you need to add WiFi connectivity to your 3040 the best bet would appear to be a USB dongle.
If you're thinking of using a AW-CM389A there is further information here.
There is a push button near the WLAN card pillar labelled 'CMCLR1' which is I assume there to let you clear the CMOS memory.
There is a push button near the battery labelled PWCLR1 which I assume is there to let you clear any set passwords.
