Hi Fernando,

the announced specs were

Hardwarespecifications:

* SOC: MediaTek MT7981B
* Wi-Fi: MediaTek MT7976C (2x2 2.4 GHz + 3x3/2x2 + zero-wait DFS 5Ghz)
* DRAM: 1 GiB DDR4
* Flash: 128 MiB SPI NAND+ 4 MiB SPI NOR
* Ethernet: 2x RJ45 (2.5 GbE + 1 GbE)
* USB (host): USB 2.0 (Type-A port)
* USB (device, console): Holtek HT42B534-2 UART to USB (USB-C port)
* Storage: M.2 2042 for NVMe SSD (PCIe gen 2 x1)
* Buttons: 2x (reset + user)
* Mechanical switch: 1x for boot selection (recovery, regular)
* LEDs: 2x (PWM driven), 2x ETH Led (GPIO driven)
* External hardware watchdog: EM Microelectronic EM6324 (GPIO driven)
* RTC: NXP PCF8563TS (I2C) with battery backup holder(CR1220)
* Power: USB-PD-12V on USB-C port (optional802.3at/afPoE via RT5040 module)
* Expansion slots: mikroBUS
* Certification: FCC/EC/RoHS compliance
* Case: PCB size is compatible to BPi-R4 and the case design can be re-used
* JTAG for main SOC: 10-pin 1.27 mm pitch (ARM JTAG/SWD)
* Antenna connectors: 3x MMCX for easy usage, assembly and durability
* Schematics: these will be publicly available (license TBD)
* GPL compliance: 3b. "Accompany it with a written offer ... to give any third party ... a complete machine-readable copy of the corresponding source code"
* Price: aiming for below 100$

So yeah: no micro sd card slot.
But you get usb and m.2 for storage which should be fine.
What is it you require one for?

Talking about SD but a bit exaggerated:
The micro SD card spec has gone to shit anyways (who even has devices with UHS-III or SD express 7.0 or 8.0? Should the micro SD card slot use UHS-III or SD express? both at the same time isn't possible even though the cards look the same). The SD card spec can't keep up with CFexpress in the camera sector.
