This is a part of the [uConsole hardware directory](https://forum.clockworkpi.com/t/22222/) and has been made its own post to make room for more content in there. This directory appears to be complete, but please reply if a board is missing. As HackerGadgets’ All-In-One Extension Board is an extremely popular card with an interesting history, I’ve given it its own section. It’s not necessarily the best card for every task; other cards have more USB ports, or more available GPIO, or support different use cases. It’s also not open hardware, like most aftermarket peripherals or the uConsole itself. It’s just a very good choice for most uConsole users and extends the uConsole’s function quite a bit. ## Extension board directory - [uConsole DIY modules](https://www.tindie.com/products/damaolvzi/uconsole-diy-modules/) designed by Lulu - comes with adaptor board, adds 1x USB3 A port, 1x USB3 C port, and NVMe for **$20 excluding shipping** - see [Tindie](https://www.tindie.com/products/damaolvzi/uconsole-diy-modules/) - uConsole expansion card designed by Lulu - adds 1x USB2 C port for **$6 excluding shipping** - see [Tindie](https://www.tindie.com/products/damaolvzi/uconsole-expension-card-single-usb20-typec/) > [@\[extension\] 4 usb hub extension board](https://forum.clockworkpi.com/t/extension-4-usb-hub-extension-board/10519/42): > > ![6A4243DD-8CB7-4AE4-9066-714565FEBC03_1_102_o](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/b/b5dbf902e9c1cc91bb4c230c252d10d8462ab631.jpeg) - [uConsole Ext USB Hub](https://forum.clockworkpi.com/t/10519) designed by @argz - adds 4x USB2 C ports - [uConsole External I/O Breakout](https://forum.clockworkpi.com/t/10415/2) designed by @57Bravo - adds 2x USB2 A ports - see [GitHub](https://github.com/57Bravo/uConsole_Ext_IO_Breakout) - open hardware - [uConsole USB Ext.

A number of RTL-SDR expansion cards were created by hobbyists before @vileer joined the scene, announcing [in a Reddit post](https://www.reddit.com/r/ClockworkPi/comments/1g1dt0z/trying_to_make_a_rtlsdr_extension_board_for/) that they were working on their own design that also added a number of USB ports to the uConsole. Eventually they [had a working prototype](https://forum.clockworkpi.com/t/14804) that also added a Real-Time Clock, or RTC, a component that keeps time when the uConsole is powered off and was sorely missing from the Raspberry Pi Compute Module 4, the most popular choice of system-on-module for the uConsole. > [@RTL-SDR Extension Board with USB HUB and RTC](https://forum.clockworkpi.com/t/rtl-sdr-extension-board-with-usb-hub-and-rtc/14804/1): > > ![bottom](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/2/2837d63a2ee52067f4fd35ca5291a352dc3a9243.jpeg) As the project progressed, it expanded considerably in scope: > [@RTL-SDR Extension Board with USB HUB and RTC](https://forum.clockworkpi.com/t/rtl-sdr-extension-board-with-usb-hub-and-rtc/14804/1): > > Maybe parts: > > 1.

RJ45 Ethernet Due to popular demand, they polished the product and created a waiting list to sell a batch of the card under the HackerGadgets brand as the uConsole RTL-SDR/LoRa/GPS/RTC/USB All-In-One Extension Board. > [@RTL-SDR Extension Board with USB HUB and RTC](https://forum.clockworkpi.com/t/rtl-sdr-extension-board-with-usb-hub-and-rtc/14804/40): > > Go and check this form [Waiting list for uConsole RTL-SDR Extension Board with USB HUB and RTC](https://forms.gle/zGPbZ1KvofY6k46d8). HackerGadgets then sold off the remaining manufactured boards on their website.

The SX1262 chip itself covers the frequency range of 150- 960MHz. However, the front-end filter is designed for 860- 960 MHz on the module. You can use it with 433MHz. However, the performance is not as good as operating at 860-960 MHz. To make your board work at its best performance, we can manually change the module to the 433-510MHz version, but that will require an extra $5(the module itself, soldering is not charged). If you want to change it and your order hasn’t shipped yet, you can contact me via the contact page on our website. The AIO cards are also useful for extremely precise timekeeping via the Global Positioning System’s Pulse Per Second service (or GPS PPS). > [@RTL-SDR Extension Board with USB HUB and RTC](https://forum.clockworkpi.com/t/rtl-sdr-extension-board-with-usb-hub-and-rtc/14804/333): > > Followed the newer version of the PPS reference: [Revisiting Microsecond Accurate NTP for Raspberry Pi with GPS PPS in 2025 - Austin’s Nerdy Things](https://austinsnerdythings.com/2025/02/14/revisiting-microsecond-accurate-ntp-for-raspberry-pi-with-gps-pps-in-2025/) This card fast became the a very popular choice of expansion for the uConsole, but vileer was dissatisfied with the AIO card as it didn’t yet include a RJ-45 port for 10BaseT Ethernet. It wasn’t long before they started to consider a major revision. > [@RTL-SDR Extension Board with USB HUB and RTC](https://forum.clockworkpi.com/t/rtl-sdr-extension-board-with-usb-hub-and-rtc/14804/103): > > ![IMG_5925](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/0/0f064b594dd0b88a56e5b916fde98fd429c8289b.jpeg) It was released as the AIOv2 with the following changes: > [@HackerGadgets' uConsole Upgrade Kit - adding NVME SSD(PCIe), RJ45 Ethernet and USB 3.0 to your Uconsole](https://forum.clockworkpi.com/t/hackergadgets-uconsole-upgrade-kit-adding-nvme-ssd-pcie-rj45-ethernet-and-usb-3-0-to-your-uconsole/20019/1): > > The AIO board(RTL-SDR/GPS/LoRa/RTC/USB HUB all-in-one expansion) will also upgrade to V2 with the following changes: USB-A on the side will be replaced by an RJ45 Gigabit Ethernet.

To resolve this issue, the resistor shown in the image below needs to be replaced with a **4.3kΩ resistor (0402 package size)**. It doesn’t need to be a 4.3kΩ resistor. The current limit threshold is calculated using the formula: I(limit) = 6.8k/Rset. The maximum current the MT9700 can handle is 2A, so the minimum resistor is 3.4kΩ. So any 0402 package size resistor with a value between 5.6kΩ and 3.4kΩ would work. > > ![](https://cdn.shopify.com/s/files/1/2067/9757/files/IMG_7793.jpg?v=1768822143) > [@Statement Regarding AIO v2 Internal USB-C Power Supply Issue and Compensation Plan](https://forum.clockworkpi.com/t/statement-regarding-aio-v2-internal-usb-c-power-supply-issue-and-compensation-plan/21131/1): > > **Affected Orders:** All AIO v2 orders shipped before last Friday (January 16). The RJ45 Ethernet and USB 3.0 expansion board is not involved. The fix is of course not necessary for units ordered since February 2026, so there’s no need for concern. If purchasing an AIOv2 secondhand, the repair can be done in an easier fashion than replacing the tiny surface-mounted resistor: > [@Statement Regarding AIO v2 Internal USB-C Power Supply Issue and Compensation Plan](https://forum.clockworkpi.com/t/statement-regarding-aio-v2-internal-usb-c-power-supply-issue-and-compensation-plan/21131/18): > > You can even just solder a discrete resistor in parallel, as shown below, without removing the 0402 resistor. The final resistance is (10k\*R)/(10k+R) . The final resistance should be greater than 3.4K.
