+<h2>Banker 128-channel TTL I/O expander</h2>
+
+<p>Banker is a versatile 128 TTL GPIO module. It has flexible connectivity and contains a small Lattice iCE40 FPGA, supported by Yosys and <a href="http://www.clifford.at/icestorm/">IceStorm</a>.</p>
+
+<p>
+Interfaces include:
+<ul>
+<li>8 x 8 channel IDC connectors, compatible with IDC-BNC and future IDC-SMA.</li>
+<li>2 x 32 channel VHDCI connectors.</li>
+<li>2 downstream EEM connectors that enable daisy-chain connection of several Banker modules.</li>
+<li>front panel DC Jack and rear side Molex supply connector.</li>
+</ul>
+</p>
+

+
+<p>All outputs can be configured either as 3.3 or 5V. They can drive 50R load when set to 5V. FPGA can is configured from on-board FLASH. FLASH can be updated over I2C or with the on-board SPI connector.</p>
+
+<p>The VHDCI connections can be used to interface with either non-buffered or buffered remote boards that distribute signals to neighboring modules. These modules can be assembled together and placed in COTS enclosures. The enclosures fit onto the low-cost and simple DIN rail standard.</p>

+
+<p>There are several DIN-rail compatible modules for use with Banker. They are interconnected using edge connectors and can be configured as mix of 4 modules of following type:
+<ul>
+<li>8 channel D-SUB</li>
+<li>8 channel BNC</li>
+<li>8 channel SMA</li>
+<li>8 channel screw terminal</li>
+</ul>

 <h2>Urukul DDS card</h2>
 <p>Urukul is a 4 channel DDS-based frequency synthesizer for the EEM form factor. It provides sub-Hz frequency resolution, controlled phase steps, and accurate output amplitude control. We offer it in two variants, with either the AD9910 or the AD9912 chip.</p>
