Lime AC Case: An active-cooling aluminum enclosure for the LimeSDR

Back this project: https://www.crowdsupply.com/hackergad... Lime AC (Active Cooling) Cases are designed for LimeSDR users who want to better manage heat generated by their devices. The cases also make LimeSDRs more portable - protecting the PCB from damage - while they provide RF shielding for enhanced performance. We’ve designed one case for the LimeSDR Mini and three versions for the LimeSDR USB Type-A. For LimeSDR Mini Compatible with both LimeSDR Mini v1.1 and v1.2 All major chips are connected to the case by 1 mm thick thermal silica pads Active cooling fan included LED indicator visible through the top of the case Fully-shielded - the vulnerable USB socket is especially protected Installation note: For the v1.0 cases (manufactured during the campaign): In order to install a LimeSDR Mini in the case, the on-board RF shield must be desoldered. This allows for proper thermal conductivity. An RF shielding sponge replaces the functionality of the on-board shield. For the v1.1 case (available after Sep 2020): we changed the heat dissipation solution for the LMS7002 chipset by connecting the original RF shield to the case, and connecting the chipset to the RF shield with the thermal pad. Previously, the chipset was directly connected to the case through a custom made RF shield. We made this change so that the heat dissipation solution won’t have any negative effect on the RF performance. The new solution looks like a sandwich: | top case | thermal pad | RF Shield | thermal pad | LMS7002 | For LimeSDR USB Type-ALime AC Case: Tetra All major chips are connected to the case by thermal silica pads On-board U.FLs routed to external SMA connectors - appropriate cables included 2 SMAs towards the USB port - intended for CLK signals 10 SMAs towards the rear - intended for RF signals LED indicators light-piped to the USB side of the case Fully-shielded - the vulnerable USB socket is especially protected All on-board RF and CLKs are made externally available Radiator fins and active-cooling fan 4 M3-5 mm mounting holes Protect Your BoardThe PCB is tightly clamped in the case. The LimeSDR Mini fits snugly in its case, while the LimeSDR-USB Type-A is fixed to the base case with screws. This design will prevent your board from being damaged if it happens to fall while installed in the case. Active Cooling with FanAnyone who uses a LimeSDR Mini for an extended period of time knows that it gets pretty hot. That’s why we added a fan to actively cool your LimeSDR so you can keep using it longer and without fear of heat damage (to the board or your hands). The fan is detachable from the case, if you don’t want to use it all the time. RF ShieldingThe full LimeSDR board is shielded by the aluminum case to isolate external electromagnetic interference. #kickstarter​ #kickbooster​ #indiegogo​ #newinventions​ #gadgets​ newinventions2021technology​ #campaign​ #advertisement​ #kickstarterproducts​ #kickstarter2021 #kickstarterprojects ⚠ If there are any copyright issues please contact us.
