Wolfram Perrey | MCHF V0.6 UI build, first light after assembly. UHSDR FW: V_2.11.55 (BL: V_5.0.4) @MrPerrey | Uploaded 4 years ago | Updated May 07 2024
This is the first light of a MCHF V0.6 UI board. The touch display is running under ISP configuration. The display is connected to the UI board by the use of a very flat SAMTEC socket (PN: CLT-120-01-F-D). The original buttons where replaced by flatter, more reliable and and smoother operating CTS Electronic buttons (222AMVBBR (h=5mm - F = 260g)). The smaller actuator force of the CTS buttons makes the push button haptic much more smoother and gives the operator a more reliable and professional user experience. With this very convenient and simple modifications the whole UI assembly also fits much better, without dragging, pushing and bending in the so called MCHF "China enclosure". The display unit remains removable by the SAMTEC socket rather then fixed by soldered connections that are time consuming difficult and risky to remove.
The assembly of the UI PCB consists of about 210 components which took about 10h for the manual placing and soldering. Flashing was done with the boot0 jumper method using the Dfu USB connection and the ST DfuSE Tool. There are two more methods to bring the UHSDR binary's in the uC. All where tested and are working grate. Boot0 Dfu method with ST DfuSE Tool is the recommended way for first light flashing. ST LinkV2 would also do the job, specially when the unit was bricked due to a broken link or mishandled flash programming.
After flashing of the UHSDR Bootloader V_5.0.4 and V_2.11.55 FW UI board fired up instantly. Board was powered by an external 5V Power Supply.
