HP t430: Hardware 

• Hardware
• Firmware
• Linux

The HP t430 was launched in May 2018. It is a physically small thin client and is intended to lie flat on a desktop. The flash and RAM are fixed and about the only option you have is what WiFi card you choose to fit in the internal M.2 slot.

The embedded operating system is one of:

• HP ThinPro
• HP Smart Zero Core
• Windows 10 IoT Enterprise

My example came with 32GB of flash and 4GB of RAM. Someone had installed ELUX as the OS. I subsequently found it must have come from the factory with ThinOS. It complained about a lack of licence when I loaded the HP Win 10 IOT OS.

Power Supply

The t430 is supplied with a 45W 19.5V 2.3A DC supply. The connector is male coaxial connector. According to my micrometer the external diameter of the barrel is 4.5mm, the internal diameter 3mm. I don't what the size is of the recessed centre pin. (April notes it is the same one as used on the t420, t640 and t740).

If you don't have an HP PSU/charger and are thinking of using a non-HP PSU see this page.

In April 2022 I heard from April:

In addition to the normal power connector the USB-C port on the side supports USB-C PD. Instead of connecting the standard power brick I plugged in a USB-C laptop charger into the USB-C socket and the t430 powered up. It uses the 20V option, so most USB-C phone chargers probably won't work, but most made for laptops will. Due to the nature of USB-C PD, any attempt to use an incompatible power adapter with this port should just result in it not working without any resulting damage. I believe the intention here is to connect it to a monitor with a single cable, carrying power (via USB PD), video (via DisplayPort alt mode) and keyboard/mouse inputs all over one connector.

CPU

The CPU fitted to the t430 is either a dual core Intel Celeron N4000 or a dual core Intel Celeron N4020. My example is fitted with a N4000.

Expansion

Flash: The t430 comes with either 16GB or 32GB of embedded NAND flash memory. The only option you have for adding storage is using one of the USB ports. At least these are USB3.1 ports.

RAM: The RAM is either 2GB or 4GB of single channel DDR4 RAM. This is embedded and can't be changed.

WiFi: The t430 has a M.2 2230 slot for a wireless network card. The HP t430 specification mentions two Intel options:

• Intel Wireless-AC 9260 with Bluetooth; M.2 module with integrated internal Wi-Fi antenna system
• Intel Dual Band Wireless-AC 8265 Wi-Fi and Bluetooth 4.2 Combo 802.11ac (1x1)

It was duly recognised as such by the Linux kernel.

02:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev ff)

From the device specs it looks like the M.2 slot carries the usual PCIe (used for WiFi) and USB (used for Bluetooth) interfaces.

In April 2022 I heard from April who had tried out her SD card adapter which hadn't worked, so confirming the absence of a SDIO interface.
