134
135 Kits are funded through a crowdfunding scheme with minimal markup.
136
137 * **DSP board** — $230 //(recalculation from alternative manufacturers expected)// Boards are supplied fully activated and connected to the update and remote servicing server.
138 * **Front panel board (with smart LEDs)** — $150
139 * **Display board (AMOLED TFT module)** — $70
140 * **PDB board** — $30
141 * **Adapter cable for PDB connection (Ethernet + USB 2.0)** — $4
142 * **Anodized front panel (new)** — $40

149 == **What level of skill is required for a self-install upgrade?** ==
150
151 ----
152
153 The upgrade kit is designed for user self-installation.
154 Basic technical knowledge and electronics skills are required:
155
156 * Install and solder the headphone and microphone jacks
157 * Reconnect internal connectors
158 * Perform assembly: secure the boards and install everything into the enclosure
159 * Set the amplifier transistor quiescent current
160 * Recalibrate output power according to the user manual
161 The work does not require professional manufacturing, but calls for care and a basic understanding of electronics principles (soldering, connecting, tuning).
162 If difficulties arise, assistance is available from:
163 **Andrey** UX4LR
164 **Pavel** UR6EA
165 Support is provided via the Telegram channel, where colleagues will help with installation and configuration questions.

174
175 Yes, of course — you can count on help if the self-install does not succeed.
176 I, as well as Pavel **UR6EA** and Andrey **UX4LR**, are ready to assist with installation and configuration.
177 In addition, a remote monitoring and configuration system via console is available. Upon user request, we can connect and promptly resolve software issues.
178 Support is also available through the Telegram channel for quick resolution of any questions.

187
188 ----
189
190 **Yes, there are several points to keep in mind:**
191
192 * The current unstable political and financial situation is affecting the components market and logistics.
193 * This has been especially pronounced in the memory market — due to sharp price spikes, the cost of memory components (DDR3 eMMC) has increased up to 5 times.
194 * As a result, the configuration had to be optimized: the eMMC capacity was reduced from 32 GB to 16 GB.
195 * Prices are currently fixed based on quotes already received from Chinese manufacturers, but they may change in the future.
196 * The first batch of DSP boards (the most expensive and critical component) is being assembled on a pre-order basis:
197
198 1. Once registration closes, the total number of participants is finalized.
199 1. An order is placed with the manufacturer for the remaining boards.
200 **Important**: Additional individual upgrades after the batch is formed are **not currently planned**, so it makes sense to decide in advance in order to be included in the current delivery.
